Ozzy Osbourne's touring OzzFest has been caught up in a rape scandal after a 20-year-old rock fan was sexually assaulted in a venue car park. The unnamed fan was attacked outside Tinley Park, Illinois, on Sunday (16JUL06) after attending the OzzFest concert there. The victim was approached by a shirtless man, who assaulted her after dragging her to a remote grassy area of the parking lot, according to local police. Tinley Park Police Commander PHIL VALOIS confirms the assault victim was from a neighbouring town in Illinois. The authorities are hunting for a 30-something white male with a muscular frame, short brown hair and possibly pierced nipples after taking a description from the victim. There were no eye witnesses.
