The deaths of 37 suspected illegal miners in Nigerian detention have triggered serious questions about the treatment of detainees and conditions inside security facilities. Families of some of the victims have accused officials of mistreatment, while authorities have launched an investigation into the deaths.
Lawan Mohammed is mourning the death of his 25-year-old son, Sulieman, who died while in the custody of the Nigeria Security and Civil Defense Corps (NSCDC) in Niger state.
Mohammed said Sulieman worked as a motorcycle mechanic and was returning home when NSCDC personnel arrested him and several other people. He said he went to the detention facility the next morning to take food to his son but instead learned that he had died.
Sulieman was among 37 detainees found dead in an NSCDC cell on Thursday. Officials said 67 people suspected of illegal mining had been held in the cell. Niger state Gov. Umar Bago said the victims may have died from suffocation.
Investigation Launched Into 37 Deaths
The NSCDC initially attributed the deaths to a possible disease outbreak. However, authorities have not yet established the exact cause of death, and an investigation is underway.
The Nigerian government has since taken disciplinary and investigative measures. On Saturday, officials announced a 10-member committee involving professionals from the legal, security, mining and medical sectors.
The government also suspended 20 additional NSCDC personnel. The agency’s Niger state commander had already been suspended.
Interior Minister Olubunmi Tunji-Ojo warned that anyone who attempts to destroy evidence, intimidate witnesses or interfere with the investigation could face serious consequences.
Mohammed has also accused officials of violently mistreating his son. He claimed Sulieman suffered severe injuries before his death. Those allegations have not been independently verified.
Families Raise Concerns Over Detention Conditions
Saba Usman also alleged that his son, Usman Whalid, was badly treated while in custody. He said his son was a student who performed casual work to support himself.
Usman claimed his son had been beaten and stepped on by officers. He said photographs and videos on his phone showed injuries to his son’s mouth and broken teeth.
The allegations add to wider concerns about detention conditions in Nigeria. The National Human Rights Commission reported receiving 371,622 complaints involving alleged rights violations in 2025. The complaints included unlawful arrest and detention, denial of justice and torture.
Security analyst Kehinde Giwa of SBM Intelligence said the deaths raise questions about detention standards, planning and accountability. He also stressed that detainees must be kept in safe conditions and receive medical care when necessary.
Survivor Describes Conditions Inside Cell
Mubarak Dahiru, one of the detainees who survived, described difficult conditions inside the facility. He said detainees were sweating heavily and repeatedly asked officials for water and food.
Dahiru also alleged that officers beat detainees and struck them with guns. His account has not been independently verified.
The Nigerian Bar Association called the deaths extremely serious and demanded a thorough, independent and transparent investigation.
Illegal mining remains a major challenge in Nigeria. Authorities and analysts have also linked illegal mining in parts of north-central and northwest Nigeria to criminal networks and armed groups. Some analysts say illicit mining can provide financial support to gangs involved in kidnappings and other crimes.
For the families of those who died, the investigation will be closely watched. They are seeking answers about what happened inside the detention facility and whether officials should be held responsible.
