37 suspected illegal miners die in Nigerian custody amid overcrowding claims

Thirty-seven people arrested on suspicion of illegal mining died inside a detention facility in Niger state, Nigeria, within two days of their arrest. The deaths have fractured an already tense situation: authorities blame disease, but intelligence reports and the families of the dead point to something far more immediate—a cell so crowded and so poorly ventilated that detainees collapsed from lack of air.

The arrests happened on a Tuesday near Borgu, an area in Niger state where small-scale gold mining has long been common. The Nigerian Security and Civil Defence Corps, the agency responsible for protecting critical infrastructure and combating illegal mining, took more than fifty people into custody. By Thursday, thirty-seven of them were dead. The NSCDC initially suggested a diphtheria outbreak had killed them, though the agency's national headquarters later acknowledged the cause remained undetermined.

The families tell a different story. Abdullahi Dalhatu, whose son was among those detained, said relatives went to the NSCDC office asking for the detainees' release but were turned away repeatedly and told to come back later. The next day, he learned his son was dead. Dalhatu believes the detainees suffocated in the cell. His son survived because he was positioned near a small window; others around him fainted in the heat and crush of bodies. Detainees knocked on the door for help, Dalhatu said, but no one came. An intelligence report shared with AFP news agency supported this account, pointing to overcrowding and inadequate ventilation as the cause of death. One relative questioned how a disease could have killed so many detainees without apparently sickening their guards.

The deaths triggered immediate unrest. Miners and relatives of the dead attacked public buildings and buses with stones and sticks before police dispersed them with tear gas. A twenty-four-hour curfew was imposed in Minna, the state capital. Niger's police chief ordered an investigation into what he called "the unfortunate death of suspected illegal miners while in the detention facility of the NSCDC." An NSCDC commander was detained as a result. The bodies were taken to the general hospital in Minna for examination.

The legal framework that should have protected these men appears to have failed at multiple points. Nigeria's constitution requires anyone detained on suspicion of a crime to be brought before a court within a reasonable time—typically within a day if a court is available within forty kilometers, or two days otherwise. It is unclear whether any of the thirty-seven had been charged or brought before a judge. An NSCDC spokesperson said more than fifty people had been arrested but not yet charged because profiling and documentation were still underway when the deaths occurred. One father told Nigerian media that his son had appeared healthy when relatives brought him food the day before he died, and he called for an independent post-mortem examination.

State Governor Mohammed Umaru Bago called the deaths "sad and tragic" during a press conference and declared three days of mourning. He also postponed the start of campaigning for elections scheduled for January. The scramble for gold in Niger state's illegal mines has long fueled criminal gang violence, according to officials and experts. Much of that gold flows into global supply chains, according to a 2024 SwissAid report. What remains unclear is whether the investigation will establish what actually killed these thirty-seven men, and whether anyone will be held accountable for the conditions in which they died.
