Immigration detainee: 'It's like a mental asylum'
The BBC has been given a rare insight into what goes on inside the UK's 13 immigration removal centres.
About 3,000 would-be immigrants are held in the centres, and although journalists are not allowed inside, the BBC's Catrin Nye managed to speak to a number of detainees by phone.
In a series of phone calls, Edwin Sandy speaks from inside Dover immigration removal centre in Kent, describing difficulties relating to other inmates and poor sanitation.
"It's like a mental asylum in here," he said. "It's crazy."
