Obliging underwear

The Guardian reports on some sort of new underwear that can raise an alarm.

Carlsen said he used the handcuffs as a tool to unscrew the hook from the wall. He ran to the door with O'Dowd lashing out at him with a metal chain. He managed to escape and ran out on to the street wearing only underwear screaming for help.

It's actually from an article about Boy George, found guilty of assault. Poor Boy George. I used to like him back in the day.
