Local officials in north-central Nigeria reported that thirty-seven people accused of illegal mining died while in custody at a detention facility in Niger state. The Nigerian Security and Civil Defence Corps (NSCDC) initially blamed an apparent disease outbreak but an intelligence report suggested overcrowding and poor ventilation led to their deaths, possibly due to suffocation as detainees were unable to get help when they collapsed. Families, including the father of one detainee who survived near a small window, described desperate attempts by those inside to seek assistance before dying from lack of oxygen in the cell.
