Poor detention conditions led to the deaths of 33 young miners held on suspicion of illegal gold mining in Minna, the capital of Niger state in central Nigeria, an official investigation has revealed. The miners, including 14 minors, suffocated after being confined for approximately 11 hours in an overcrowded, poorly ventilated cell operated by the Nigeria Security and Civil Defence Corps (NSCDC), a paramilitary agency.

The incident occurred in September when the detainees were placed in a 20-square-meter cell designed to hold far fewer occupants. According to the investigative panel, the overcrowded facility had inadequate airflow, no running water, no functioning toilet, and a solid metal door that hindered ventilation. Survivors reported being packed tightly inside the cell, screaming and banging on the door for help, but guards assigned to nearby duties failed to respond.

Jonathan Kure, head of the investigation, said medical and forensic examinations confirmed that the cause of death was environmental asphyxia and acute respiratory failure due to heat stress, dehydration, and the prolonged confinement in an overcrowded environment. The report described the circumstances as amounting to "cruel, inhuman and degrading treatment," highlighting "gross leadership failure," institutional weaknesses, and serious misconduct by the officers involved.

Initial reports from Niger state officials placed the death toll at 37, but the panel established 33 fatalities. The NSCDC had previously attributed the deaths to disease, a claim the investigators dismissed as unfounded. The panel pointed to systemic issues, including unlawful detention practices and neglect of detainees’ distress signals, as contributing factors to the tragedy.

The inquiry recommended summary dismissal of the implicated officers alongside criminal prosecutions for charges including murder, negligence, torture, and inhuman treatment. Interior Minister Tunji-Ojo pledged to suspend any personnel found to have concealed evidence or obstructed the investigation. The cell where the deaths occurred was reportedly cleaned and disinfected before investigators arrived.

In addition to criminal accountability, the report suggested compensation payments of 30 million naira (approximately $22,360) to each family of the deceased and 10 million naira ($7,450) to surviving detainees. The tragedy has underscored longstanding concerns about Nigeria’s detention system. A United Nations Subcommittee on Prevention of Torture visited Nigeria in 2024 and described conditions in many detention centers as "abysmal," urging urgent reforms to prevent torture and improve detainee welfare.

Human rights advocates, including Funke Adeoye, founder of Hope Behind Bars, regularly highlight severe overcrowding in Nigerian detention facilities, often holding three times their intended capacity. Niger state, a mineral-rich region more than twice the size of Belgium, draws thousands of artisanal miners seeking gold. However, illegal mining activities have fueled violence and operations by armed criminal groups, locally known as bandits, further complicating regional security and law enforcement challenges.
