The Spanish Interior Minister, Juan Ignacio Zoido, acknowledged, following two and a half months of the act, that 11 migrant children were locked up in Archidona prison.
The Minister highlighted that those youngsters were moved into the care of the Andalucian authorities once their age was known.
The official added that up to 89 people were released – 63 for asylum reasons, 11 for humanitarian issues, three for precautionary reasons and one who was not believed to be Algerian.
In this aspect, the treatment of the nearly 600 migrants put in the prison was widely and angrily condemned by rights groups, opposition parties, charities and the United Nations (UN).
For his part, Mr Zoido claimed that Mohamed Bouderbala, who died in the prison, was “encouraging” a riot that occurred in the days before his death, condemning “conspiracy theories” about the death, according to Spanish press.
Earlier, video footage appeared to show a man lying face down outside of a cell. The Algerian government is investigating the death, following claims from inmates that he died after being beaten by police and kicked in the head.
Before all the migrants left the makeshift facility, there were reports that three of them had begun self-harming.
One riot at the facilities led to reports of the use of tear gas, rubber bullets, batons and riot police.
