What Led to the Deaths of 37 Suspected Illegal Miners in Niger?

The reported deaths of 37 people in the custody of the Nigeria Security and Civil Defence Corps (NSCDC) in Niger State have raised questions about what happened to the detainees, the circumstances surrounding their deaths and the actions taken by authorities.

The deceased were among people arrested during enforcement operations against suspected illegal mining in the Wushishi-Lukoto area of Niger State on September 15 and 16, 2026. The National Human Rights Commission (NHRC) said the bodies were later deposited at the General Hospital in Minna.

However, questions remain about the cause of death. While the NSCDC initially linked the deaths to a suspected disease outbreak, survivor accounts later raised allegations about overcrowding and the spraying of an unidentified substance inside the detention facility. Reuters reported that the accounts could not be independently verified and that no definitive cause of death had been established.

What happened to the 37 people?

The Federal Ministry of Interior said 37 people being held by the NSCDC Niger State Command on suspicion of illegal mining died in custody on September 17, 2026.

The ministry said the deaths prompted the Federal Government to constitute a 10-member independent investigative committee to establish the identities of the deceased, examine the circumstances surrounding their arrest and detention, and determine the cause and manner of death.

The NHRC separately said the detainees had been arrested during enforcement operations in the Wushishi-Lukoto area on September 15 and 16 before their bodies were deposited at the General Hospital in Minna.

Were the 37 people confirmed to be illegal miners?

Official statements describe the deceased as people who were suspected of illegal mining or suspected to be artisanal miners. The Federal Ministry of Interior specifically said the 37 people were being held on suspicion of illegal mining.

This distinction is important because being arrested or detained on suspicion of an offence is not the same as being convicted of that offence. The NHRC also stressed that suspicion of illegal mining does not remove the constitutional rights of people in custody, including their right to be treated with dignity.

What caused their deaths?

The cause of death has not been conclusively established. The NSCDC initially attributed the deaths to a suspected disease outbreak.

However, Reuters later reported that survivors described severe overcrowding in the detention facility and alleged that an unidentified substance was sprayed into the cell before some detainees developed breathing difficulties and collapsed. Reuters said it could not independently verify those accounts or determine what substance was involved.

The Federal Ministry of Interior has therefore directed the investigative committee to establish the cause and manner of death through appropriate medical and forensic examination.

This means claims that the detainees died from poisoning, suffocation or a particular chemical exposure should not be presented as established facts until the investigation and forensic examination determine the cause.

What did survivors say happened inside the detention facility?

Survivors interviewed by Reuters alleged that nearly 70 detainees had been held in a cell measuring about five square metres.

They also alleged that an unidentified substance was sprayed inside the cell and that some detainees subsequently experienced breathing difficulties before collapsing.

Reuters noted that it could not independently verify the accounts or establish what substance, if any, had been sprayed. The allegations are therefore part of the evidence being examined, rather than a confirmed explanation for the deaths.

What does the medical evidence show?

Reuters reported that examinations had been conducted on three bodies, with observations including blistering and the discharge of brown fluid. Further samples were expected to undergo laboratory analysis. These observations alone do not establish what caused the deaths. Determining the cause requires medical and forensic examination, which is also part of the mandate of the Federal Government’s investigative committee.

How many people were arrested?

Reports have referred to different numbers of people arrested during the mining enforcement operations. 

The NHRC confirmed that the deceased had been arrested during operations in the Wushishi-Lukoto area on September 15 and 16. However, the number of people initially arrested should not be treated as the same as the number who later died in custody.

For this reason, the clearest established figure for the deaths is 37, while other figures concerning the total number of detainees should be attributed to the specific source reporting them.

What happened to the NSCDC officers involved?

The Federal Ministry of Interior said the Niger State NSCDC Commandant and 20 other officers were suspended pending the outcome of the investigation.

The ministry said the committee would investigate whether negligence, misconduct, complicity or breaches of duty occurred and recommend appropriate disciplinary action where necessary. The suspension should not be interpreted as proof that the officers caused the deaths. It is an administrative measure pending the outcome of the investigation.

What investigations are underway?

The Federal Government has established a 10-member independent investigative committee to examine the incident.

According to the Ministry of Interior, the committee is expected to establish the identities of the deceased, investigate their arrest and detention, determine the cause and manner of death, establish whether negligence or misconduct occurred, and recommend appropriate action where necessary. It is expected to submit its report within two weeks.

The NHRC has also commenced a preliminary investigation and called for an independent forensic autopsy and preservation of evidence. Niger State Government has separately inaugurated a commission of inquiry to investigate the deaths. The existence of multiple investigations means the final explanation for what happened is still pending.

Why does the cause of death matter?

The cause of death is central to determining what happened inside the detention facility and whether any individual or institution bears responsibility.

The Federal Government’s investigative committee has specifically been tasked with determining whether negligence, misconduct, complicity or a breach of duty occurred. The committee is also expected to examine the circumstances surrounding the arrests and detention of the deceased.

Until those investigations are completed, allegations about how the detainees died should be distinguished from findings established through forensic and documentary evidence.

What does the evidence show?

The evidence currently establishes that 37 people died while in NSCDC custody in Niger State after being arrested during operations against suspected illegal mining.

It also establishes that the Federal Government has constituted an independent investigative committee and suspended the officers involved pending the outcome of the investigation. The NHRC has separately commenced a preliminary investigation and called for independent forensic examination.

However, the available evidence does not yet establish a definitive cause of death.

Survivor accounts alleging overcrowding and exposure to an unidentified substance require further investigation, while the initial explanation of a suspected disease outbreak has also not been established as the definitive cause.

The Federal Government’s committee has been mandated to use medical and forensic evidence to determine the cause and manner of death.
