Thirty seven detainees died in the custody of the Nigeria Security and Civil Defence Corps (NSCDC) in Niger State on September 17, two days after security personnel arrested 67 people during mining enforcement operations around the M.I. Wushishi and Lukoto areas of Minna.

What happened inside the detention facility remains the subject of an official investigation. But interviews with survivors, relatives and former detainees raise questions about overcrowding, the circumstances of the arrests, alleged demands for money and the conditions in which the detainees were held.

Families say they began trying to secure the release of relatives almost immediately after the arrests. Some allege they were asked for cash. Others say their loved ones were not miners and should never have been detained.

Now, the Federal Government has suspended officers linked to the incident and established a 10 member investigative committee to determine how the detainees were arrested, detained and died.

The central question is no longer simply how 37 people died.

It is how 67 people came to be confined in a facility that, according to people familiar with it, was designed to hold fewer than half that number and why some of those detainees were still there when the deaths occurred.

The arrests took place on September 15 and 16 around the M.I. Wushishi and Lukoto areas of Minna during an operation targeting suspected illegal mining.

A survivor interviewed by Globalvoice said 67 people were packed into a room intended for about 25.

A retired NSCDC officer who previously served in the Mining Unit independently told Globalvoice that the holding cell's standard capacity was between 20 and 25 people.

If those accounts are accurate, the facility was holding more than twice its reported capacity.

The Federal Government has suspended officers implicated in the incident and inaugurated a 10 member independent committee to establish what happened from the arrests through the detention to the deaths.

The findings could determine whether the deaths resulted from a failure of detention procedures, medical neglect, overcrowding or other factors.

For some families, the tragedy began before they received news of the deaths.

Hadiza Umar, 48, whose son died in custody, said she was asked for ?100,000 to secure his release on September 16.

“I had only ?20,000 and was told it was insufficient,” she said.

Fatima Jibrin, whose husband also died, said her husband was not a miner but sold sachet water at a mining site.

“They arrested everyone. Now they say 37 died of disease. My husband was healthy,” she told Globalvoice.

The accounts raise questions that the government investigation will have to answer: Who exactly was arrested? What legal basis was used to detain them? Were detainees given access to medical care? And what happened when relatives tried to secure their release?

Globalvoice earlier reporting established that 67 people were detained during the September operation and that 37 subsequently died.

The same reporting cited a security official who said the holding facility was designed for 20 to 25 people, while a medical officer who received the bodies at General Hospital Minna described dehydration and exhaustion among some of the deceased.

The precise cause of death, however, has not been conclusively established.

For Hafsat Saidu, the detention facility was not unfamiliar.

She had previously spent five days there after being arrested at a mining site during an earlier operation, according to an account she gave TheCable.

She said her family paid ?45,000 before she was released. According to her account, ?10,000 was demanded for bail and another ?5,000 for home verification. She also alleged that ?10,000 was demanded from another detained woman.

Globalvoice separately interviewed Hafsat's daughter, Zainab Saidu, who said the family brought food to her mother during the five-day detention and eventually paid ?45,000 before her release.

Then came the September operation.

Hafsat said her children were among those arrested.

One survived.

Another died.

The family's experience places a human timeline around the investigation: a mother who had already experienced detention at the facility watched her children enter the same system, only for one of them not to return.

Survivors Describe a Cell in Crisis

Survivors interviewed by TruthNigeria described extreme overcrowding and deteriorating conditions during the detention.

Dauda Shehu said 67 people were confined in a room intended for about 25.

“There was no air,” he said, describing detainees vomiting and calling for help. He alleged that the door was not opened until the following morning, when bodies were discovered.

Another survivor, Zayyanu Idris, said his family secured his release on September 16.

“I was lucky, my family paid quickly and I left at 10 am on the 16th,” he said, adding that the cell already had a strong smell and that people who remained inside died later that night.

Reuters separately reported survivor accounts describing severe overcrowding and an allegation that an unidentified substance was sprayed inside the cell.

That allegation has not established the cause of the deaths.

The deaths remain under investigation.

Accounts from former detainees suggest that overcrowding and alleged payment demands may not have begun with the September operation.

Ibrahim Dangana, a miner who said he was detained at the facility in March, described sleeping while standing in shifts with about 35 other people.

“They told us to bring ?50,000,” he said.

John Okafor, a former NSCDC Mining Unit superintendent, told TruthNigeria that the cell's standard capacity was 20 to 25 people.

He also said payments for home verification were not part of the Corps' standard operating procedure.

If the accounts are corroborated, investigators may have to determine whether the September tragedy was an isolated breakdown or the culmination of practices that had existed for months.

A separate line of inquiry concerns the financial pressures surrounding mining enforcement operations.

A serving senior NSCDC officer with direct knowledge of mining-enforcement activities spoke to Globalvoice on condition of anonymity, citing concerns about professional repercussions.

The officer alleged that financial-return expectations influence some mining-enforcement postings and that pressure to generate money can encourage more arrests and prolonged detention.

The source further alleged that money generated through such activities moved upward through the command structure.

Those allegations have not been independently established and should be tested by investigators examining financial records, operational orders, arrest logs and communications within the command.

If verified, they would raise a question extending beyond the deaths themselves: whether financial incentives influenced who was arrested, how long people were detained and how the operation was conducted.

The government's 10 member investigative committee now faces a series of fundamental questions.

Who authorized the arrests?

What criteria were used to identify suspected illegal miners?

How many of the 67 detainees were actually miners?

Why were so many people held in a facility reportedly designed for 20 to 25?

Were detainees provided adequate food, water, ventilation and medical attention?

Were families asked for money to secure releases?

Were any payments authorized under NSCDC procedures?

What happened inside the cell during the final hours?

And what caused the deaths of the 37 detainees?

Lt. Col. Usman Babangida (rtd.), a former tactical training officer and security consultant, said the reported numbers alone warrant scrutiny.

“Holding 67 people in a cell designed for 20 to 25 would be inconsistent with basic detention practice,” he said, arguing that investigators should examine whether arrest decisions were influenced by considerations beyond security enforcement.

The answers will determine whether the September 17 deaths were the result of a catastrophic detention failure or whether deeper problems in mining enforcement, arrest practices and custodial oversight helped create the conditions in which 37 people died.

For the families waiting for those answers, the investigation is not an abstract exercise.

They want to know how their relatives were arrested, why they were still behind bars, and why they did not come home alive.
