The death of 37 suspected illegal miners while in the custody of the Nigeria Security and Civil Defence Corps (NSCDC) in Niger State has triggered outrage, protests, official suspensions and a broad investigation by federal and state authorities.
TheNewsGuru (TNG) reports the victims were among dozens of people arrested during enforcement operations against suspected illegal mining in the M.I. Wushishi/Lukoto axis of Niger State on September 15 and 16, 2026.
The NSCDC initially said the deaths followed a suspected disease outbreak, but the Corps subsequently acknowledged that the actual cause had not been established. Medical, laboratory and forensic examinations are expected to determine what happened.
President Bola Tinubu has ordered a full and transparent investigation, while the Niger State NSCDC Commandant, Suberu Siyaka Aniviye, has been suspended.
The Niger State Government has also constituted an investigative committee and imposed a 24-hour curfew in Minna following protests and destruction of property linked to the deaths.
Here is what is known so far.
How did the miners end up in NSCDC custody?
TNG reports the detainees were arrested during operations by the NSCDC against suspected illegal mining in the M.I. Wushishi and Lukoto areas of Niger State.
It was gathered that the operation followed concerns over illegal mining activities in the communities, with the NSCDC saying the arrests took place on September 15 and 16.
According to reports, 67 artisanal and suspected illegal miners were detained in an NSCDC facility. Governor Umaru Bago subsequently disclosed that 37 of them died while in custody.
The NSCDC had said the operation was part of efforts to enforce government directives against illegal mining.
The precise identities and ages of all those detained, as well as the individual circumstances of their arrests, remain matters for the ongoing investigations.
Police have separately commenced an investigation into the deaths, with the Deputy Commissioner of Police in charge of the State Criminal Investigation Department directed to take over the case.
When did the deaths occur?
It was gathered that the deaths were discovered in the early hours of Thursday, September 17, after the suspects had been detained during the preceding two days.
TNG reports the Niger State NSCDC initially described the deaths as following a suspected disease outbreak.
In its initial account, the Corps said the cause had not been conclusively established and that medical examinations would be required to determine what happened.
However, the bodies were taken to the General Hospital in Minna for examination.
That initial explanation has since become one of the central questions surrounding the incident because of the number of people who died within a short period while in government custody.
What caused the deaths?
TNG reports that there is no confirmed official cause of death as of the time of filing this report.
The NSCDC initially referred to a suspected disease outbreak, but the Corps has not established a particular disease as the cause.
Governor Bago has said forensic examinations, medical examinations and autopsies are being conducted to establish the scientific cause of the deaths.
Reports have raised other possibilities, including overcrowding, inadequate ventilation and possible exposure to hazardous substances associated with mining activities.
Governor Bago was quoted as saying authorities were considering possible suffocation from overcrowding and exposure to hazardous substances, but these remain possibilities under investigation rather than established causes.
Some relatives and survivors have also alleged that detainees were held in overcrowded conditions and experienced difficulty breathing.
TNG reports those allegations have not yet been independently established as the cause of the deaths.
Reuters reported that the NSCDC later said the exact cause remained unknown pending medical investigation.
Consequently, claims that the 37 miners were killed by suffocation, disease, poisoning or any other specific cause cannot be treated as established fact until the medical and forensic investigations are concluded.
Why has the incident generated so much outrage?
The deaths occurred while the victims were in the custody of a government security agency.
That fact has intensified concerns over the conditions in which the detainees were held and whether adequate measures were taken to protect their lives and provide medical attention.
The controversy has also been fuelled by accounts from relatives and survivors.
Reuters reported that the mother of one detainee, Shafa’atu Suleiman, said she had visited her son Abdullahi in detention and found him in a cramped cell before later learning of his death.
She alleged that relatives were prevented from delivering food to detainees and that money was demanded for their release. The allegations have not been independently verified, while the NSCDC did not respond to Reuters’ requests for comment on them.
Other relatives have disputed the claim that everyone arrested was involved in illegal mining.
Premium Times reported allegations from relatives that some detainees were arrested while engaged in other activities, although those claims had not been independently verified.
The circumstances surrounding each arrest, therefore, form another important part of the investigation.
Were children among the dead?
Reports indicate that some of those detained were young.
Governor Bago told Reuters that many of the dead were children between 14 and 18 years old, who had been working in mining sites instead of attending school.
Other reports have carried claims by relatives concerning even younger detainees. Those claims have not been independently verified.
The identities, ages and circumstances of all 37 deceased persons will, therefore, be significant to the investigation.
Establishing who the victims were is also necessary for their families to receive accurate information and for investigators to reconstruct what happened to each detainee.
What has President Tinubu done?
Meanwhile, President Tinubu has ordered a full and transparent investigation into the deaths.
The President said the investigation should examine the circumstances of the arrests, the condition of the detainees when they were taken into custody, the conditions in which they were detained, the number of people held at the facility, the medical attention provided to them and the events leading to their deaths.
Tinubu also directed that any official found to have contributed to the deaths through abuse, negligence or dereliction of duty should be arrested and prosecuted in accordance with the law.
“The suspension of officers is only an administrative step and must not substitute for a proper determination of criminal responsibility where the evidence warrants prosecution,” the President said.
He also stressed that the Federal Government would continue its fight against illegal mining but that enforcement operations must comply with the law and respect the rights of people in custody.
“The fact that these individuals were suspected of illegal mining does not in any way remove their right to life, dignity and humane treatment while in government custody,” Tinubu said.
Why was the Niger NSCDC Commandant suspended?
The Federal Government suspended Suberu Siyaka Aniviye, the NSCDC Commandant in Niger State, following the deaths.
The suspension was ordered by Interior Minister Olubunmi Tunji-Ojo as investigations into the incident commenced.
President Tinubu has specifically said that administrative suspension must not replace an investigation into possible criminal responsibility.
The investigation is expected to establish what happened, who was responsible for decisions concerning the detainees and whether any official breached established procedures.
What is Minister Tunji-Ojo doing?
The Minister of Interior, Olubunmi Tunji-Ojo, has ordered a full investigation into the deaths and suspended the Niger State NSCDC Commandant.
The NSCDC is under the Interior Ministry, making the ministry central to the Federal Government’s response.
Tunji-Ojo has said the circumstances surrounding the deaths must be properly investigated and that the suspended commandant will remain out of office while the process continues.
The investigation will, therefore, involve examining not only the immediate circumstances of the deaths but also the actions of officers responsible for arrest, detention, supervision and medical care.
What role is Dele Alake playing?
The Minister of Solid Minerals Development, Dele Alake, has also moved to establish what happened.
Alake announced the deployment of a “high-powered team” of officials to Niger State to investigate the circumstances surrounding the deaths and establish the facts.
“Given the allegation that the detained persons were arrested on suspicion of carrying out illegal mining, I have deployed a high-powered team of officials to Niger State to investigate the circumstances and ascertain the facts of the matter,” Alake said.
He added that the team would collaborate with other investigators to produce a comprehensive report.
Alake also described the deaths as a tragedy and expressed condolences to the Niger State Government, the families of the deceased and affected communities.
He said a thorough, transparent and independent inquiry was necessary to establish accountability and prevent similar incidents in detention and correctional facilities.
What has the Niger State Government done?
Meanwhile, Governor Umar Bago has described the incident as tragic and confirmed that 37 detainees died in NSCDC custody.
The state government has constituted a committee to investigate the circumstances surrounding the deaths.
Bago said forensic examinations, medical examinations and autopsies were being undertaken to establish the scientific cause of death.
The state government has also declared a period of mourning and appealed for calm.
But the situation deteriorated as protests erupted in Minna.
How did the protests begin?
Anger over the deaths spilled onto the streets of Minna on Thursday and Friday. Hundreds of people reportedly gathered to demand answers over the deaths of the detainees.
The protests subsequently became violent in parts of the city, with reports of vandalism and attacks on government and private property.
Reuters reported clashes between protesters and security forces, saying security personnel fired live ammunition during the unrest. AP, in its account, reported that police fired tear gas to disperse demonstrators.
Why was a curfew imposed?
Following the unrest, Governor Bago imposed a 24-hour curfew in Minna. The restriction was announced after incidents of vandalism and destruction of property linked to the protests.
Reports said the curfew took effect after Friday’s Jumu’ah prayers. The measure was aimed at restoring order amid heightened tension in the state capital.
Reports of the curfew have sometimes described it as a Niger State-wide restriction, but the detailed reports from the state government and major news organisations identify Minna as the area under the 24-hour restriction.
What properties were reportedly affected?
The unrest reportedly resulted in damage to both public and private property.
According to reports, the Niger State Transport Company’s buses, a Sterling Bank branch, political party offices and private businesses were among properties affected by the violence.
What happens next?
The immediate focus is on the medical and forensic evidence and the findings of the various investigations.
The government has already made clear that the suspension of the NSCDC commandant is not the conclusion of the matter.
President Tinubu has directed that anyone found responsible through abuse, negligence or dereliction of duty should face prosecution.
At the same time, the Federal Government has maintained that the fight against illegal mining will continue.
That creates a difficult balance for the authorities: tackling illegal mining while ensuring that enforcement agencies themselves operate within the law.
For the families of the 37 deceased persons, however, the immediate question is more basic — how did their relatives die while in government custody?
Until the medical examinations, forensic work and investigations provide a definitive answer, the precise cause of the deaths remains unknown.
What is established is that 37 suspected illegal miners died after being detained by the NSCDC in Niger State; the deaths occurred in government custody; the Niger State NSCDC commandant has been suspended; several investigations are underway; President Tinubu has ordered a comprehensive probe; and public anger over the incident has led to protests and a 24-hour curfew in Minna.
The next phase of the investigation will determine whether those facts lead to findings of negligence, misconduct or criminal responsibility — and whether the authorities can provide the families and the wider public with a credible account of what happened.
