Authorities in Niger State imposed an overnight curfew in Minna after protests over the deaths of 37 detainees who had been held by the Nigeria Security and Civil Defence Corps following arrests linked to suspected illegal mining.

The deaths triggered demonstrations in the state capital on Friday, with police using tear gas as crowds demanded answers. Reuters reported that security forces later restored order ahead of the curfew, while Associated Press reporting said the protests centred on the circumstances surrounding the detainees' deaths in custody.

What is known so far

The detainees had been arrested during operations targeting suspected illegal mining activity in Niger State. The NSCDC initially referred to a possible disease outbreak, but its national leadership later said the precise cause of death had not been established and would be determined through medical investigation.

Survivors have alleged that detainees were held in an overcrowded and poorly ventilated cell. Those claims have not been independently established as the cause of the deaths and remain part of the wider investigation.

President Bola Tinubu ordered an investigation into the incident, while senior NSCDC officials in Niger State were suspended pending the outcome. Federal officials have said anyone found culpable should face consequences, while also cautioning against prejudging the investigation.

Curfew follows protests in Minna

Protests escalated in parts of Minna as residents, miners and relatives of the dead demanded accountability. Reuters reported clashes between demonstrators and security forces, while AP reported that police used tear gas to disperse crowds near the civil defence corps office.

Niger State authorities subsequently imposed an overnight curfew beginning at 6pm in an effort to restore order and prevent further violence.

Cause of death remains under investigation

The most important unanswered question remains what caused the 37 deaths. Public accounts currently differ: the NSCDC initially mentioned a suspected illness, while survivors described overcrowding and poor ventilation. Until medical and forensic findings are completed, neither explanation should be treated as definitive.

The investigation is expected to examine the conditions of detention, the actions of officials responsible for the detainees and the sequence of events from arrest to death.

Why the case matters

The incident has intensified scrutiny of detention practices, enforcement around illegal mining and accountability within security agencies. It also highlights the difficult balance between tackling illegal mining and ensuring that suspects' basic rights and safety are protected while in government custody.
