The Nigeria Security and Civil Defence Corps (NSCDC) has ordered an investigation into the deaths of 33 suspected illegal miners who reportedly died after being arrested during an enforcement operation in Niger State.

The detainees were apprehended during a joint operation targeting illegal mining activities around the M.I. Wushishi/Lukoto axis of the state on September 15 and 16, 2026.

According to the Niger State Command of the NSCDC, the deaths were discovered in the early hours of Thursday, September 17.

The circumstances surrounding the deaths remain unclear, with the Corps cautioning against attributing them to any particular disease or condition before medical examinations and laboratory tests are completed.

The remains of the deceased have been evacuated to the General Hospital in Minna, where medical examinations are expected to help establish the actual cause of death.

NSCDC Launches Investigation Into Niger Deaths

In a statement issued by the Corps’ National Public Relations Officer, Assistant Commandant of Corps Babawale Afolabi, the Commandant General, Prof. Ahmed Abubakar Audi, ordered the immediate establishment of a high-powered investigative team.

The team is being led by the Deputy Commandant General responsible for Intelligence and Investigation.

Its mandate is to establish what happened before, during and after the suspects were taken into NSCDC custody.

Investigators are expected to examine several aspects of the incident, including the physical condition of the detainees when they were arrested, the length of time they spent in custody and the conditions in which they were held.

The investigation will also examine the medical attention provided to the detainees and any other circumstances that may have contributed to the deaths.

The NSCDC said it was collaborating with health authorities and other security agencies to put appropriate medical and public-health measures in place following the incident.

The Corps has also directed that the health and welfare of suspects who remain in custody receive immediate attention.

Personnel who may have come into contact with the affected detainees are also being protected as part of the measures being implemented.

The Commandant General cautioned against premature conclusions about the cause of the deaths, stressing that the matter would be addressed based on verified medical and investigative findings.

The incident occurred amid the NSCDC’s continuing enforcement activities against illegal mining, an activity the Corps said it would continue to combat.

However, the security agency stressed that enforcement operations must be conducted alongside respect for the dignity and fundamental rights of individuals placed in custody.

Audi expressed condolences to the families of the deceased and assured them that the circumstances surrounding the deaths would be thoroughly examined.

The Corps also appealed for calm while the medical examinations and investigation continue.

The NSCDC said additional information would be made public as verified facts emerge from the ongoing processes.

The investigation is expected to determine whether the deaths were connected to medical conditions, circumstances surrounding the arrests or detention, or other factors.

Until the relevant examinations and investigations are completed, the cause of death of the 33 detainees remains unconfirmed.

The development has therefore placed attention on both the enforcement of laws against illegal mining and the responsibility of security agencies to safeguard the wellbeing of persons in their custody.
