American lifestyle queen Martha Stewart found herself in trouble with jailers while she was serving her stock fraud sentence in West Virginia - for not reporting a bruise.

Warders at Alderson Federal Prison Camp felt sure Stewart had been fighting with other inmates when they first saw the mark on her arm and she was called in to explain what had happened.

She recalls, "One day I fell against the wall, I slipped on some wet floor and I got a really bad black and blue mark on my arm.

"You have to report any injuries, which I didn't know."
