Authorities in Nigeria's Minna state discovered 33 detainees dead on 17 September while held by the Nigeria Security and Civil Defence Corps. The individuals were detained on suspicion of illegal mining, despite the fact that the mining sites had been licensed.

Severe overcrowding, poor ventilation, and a failure by officers to respond to distress calls caused the fatalities. Medical evidence indicates the victims suffered from acute respiratory failure linked to prolonged confinement, heat stress, and dehydration.

Investigators found no evidence to support initial claims that a disease outbreak occurred. Interior Minister Olubunmi Tunji-Ojo stated that those responsible for the deaths would face the full force of the law.

The minister noted that the detention hall had been cleaned before investigators arrived and confirmed that implicated officers will face suspension. Fifty detainees were held in a cell measuring about 20 sq m that lacked running water, a functioning toilet, adequate food, drinking water, and airflow.

Adults and minors were detained together, and some detainees were held beyond lawful detention periods. Officers reportedly ignored repeated calls for help.

Jonathan Kure said, "Detainees repeatedly banged on cell doors and walls, shouted for assistance and pleaded for water." Kure stated, "The tragedy demonstrates the consequences of systemic disregard for detention standards, supervisory responsibilities and the welfare of persons in custody."

An investigating committee recommended compensation of 30m naira for each of the bereaved families. The committee also recommended 10m naira for each survivor.
