The dangerous criminal helped by hospital where Ian Brady lives
They're home to some of the most violent offenders in the country.
High-security psychiatric hospitals, including Broadmoor in Berkshire and Ashworth on Merseyside, have housed prisoners such as the Yorkshire Ripper Peter Sutcliffe, the Moors murderer Ian Brady.
Both of them will never be released, but many others who commit lesser crimes are eventually freed.
Our social affairs correspondent Michael Buchanan joined one of them for a rare look inside Ashworth, and he sent this report.
