Chicago, October 17 (RHC)-- In the U.S. city of Chicago, a man who says he was tortured by Chicago police officers into confessing to a murder he did not commit has been released from prison after spending a quarter of a century behind bars.

Shawn Whirl says he was slapped, stepped on, and cut with a set of keys by a detective working under Chicago Police Commander Jon Burge, who has been convicted for lying about torturing prisoners into making confessions.

Under Burge’s reign from 1972 to 1991, more than 200 people, most of them African-American, were tortured with tactics including electric shocks and suffocation. Shawn Whirl walked free after a quarter of a century in U.S. prisons.
