Immigration detainee: 'I don't know why they're torturing us'
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 emotional phone calls, Shinda Bajwa spoke from inside Harmondsworth immigration removal centre in Middlesex, describing how he stayed in his room all day, crying.
"It's worse than prison," he said. "I don't know why they're torturing us."
