Usman Muhammad pauses by the entrance to a tiny Nigerian prison cell and leans his forehead against the wall unable to speak.
The day before he had been trapped inside the stifling room, measuring roughly 6m (19.7ft) by 3m (9.8ft), with more than 50 other prisoners.
Thirty-three of his cellmates died in the cramped conditions in the prison in Minna, the capital of Nigeria's Niger state - and four died later in hospital.
The prisoners were held at its detention centre in the city, but the NSCDC has not shared either the names or the number of those it was holding.
