A piece of penmanship from hardened felon Charles Bronson has been removed from a platform on Angel Tube station. The work, depicting a three-headed man in a straitjacket, had reportedly caused offense to a victims' group, who were dismayed at the exposure given to an armed robber and hostage taker. But here's the mystery. The art work has not been removed by London Underground in knee-jerk appeasement—at least officially. And no act of theft or vandalism has been reported. Has someone taken Bronson hostage?
