Niger State authorities suspended all mining activity across the state and imposed a round-the-clock curfew in the state capital, Minna, after 37 people detained during a crackdown on suspected illegal gold mining died in custody, an outcome that sparked protests and set off multiple investigations.

The Nigeria Security and Civil Defense Corps arrested scores of people at mining sites near Minna on Monday and Tuesday as part of an operation against unlicensed mining. Authorities discovered on Thursday that 37 of those detained had died, though the cause of death had not been established at the time.

Niger State Governor Mohammed Umaru Bago said overcrowding may have been to blame. "It could be as a result of suffocation because there were so many in a cell," he said. In response, the state government ordered forensic examinations and autopsies of the deceased and opened separate investigations through the police, the State Security Service and the civil defense corps.

At the federal level, Interior Minister Olubunmi Tunji-Ojo suspended the Niger State commandant of the civil defense corps pending the outcome of a federal investigation into the deaths. The corps' national leadership subsequently sent a replacement commandant to take over operations in the state.

Amnesty International urged that an independent investigation be carried out and said minors were among those detained, an allegation that could not be independently confirmed [uncertain].

The episode has placed renewed scrutiny on Nigeria's Mining Marshals program, a unit drawn from the civil defense corps that the federal government established in 2024 specifically to crack down on unlicensed mining nationwide. Between March 2024 and August 2026, the unit identified 374 suspected illegal mining sites and cleared 108, while arresting 743 people in connection with illicit mining activity. Of the 165 cases that made it to prosecution over that period, only five resulted in convictions, a gap between arrests and successful prosecutions that had already raised questions about the program's effectiveness before this week's deaths.

Illegal and artisanal mining is a persistent challenge in parts of Nigeria, and the program was intended to give civil defense personnel a dedicated mandate to identify and shut down unlicensed sites and detain those operating them.

This week's deaths, however, have shifted the public conversation from the underlying problem of illegal mining to the conduct of the crackdown itself, including how many people were held in a single cell, what oversight existed over detention conditions, and how quickly the state responded once the deaths were discovered. The suspension of both legal and illegal mining operations across Niger State, along with the Minna curfew, is intended to contain the immediate fallout while the various investigations proceed.

It remains unclear how long the mining suspension and curfew will stay in place, what specific findings the forensic examinations will produce, or whether any officials will face criminal liability once the police, State Security Service and civil defense corps investigations are complete. The federal government's decision to install new leadership over the civil defense corps in Niger State signals that Abuja views the episode as serious enough to warrant an immediate change in command even before the investigations conclude.
