Teen idol Justin Bieber is wanted for questioning by Los Angeles County Sheriff's investigators - after a paparazzo complained of being roughed up by the young pop star at a shopping center. The scuffle allegedly happened when the photographer tried to snap pictures of the 18-year-old and his girlfriend Selena Gomez, after they walked out of a theater at The Commons at Calabasas today. Sheriff Lt. Robert Wiard says the photographer in question called 911 on Sunday and complained of pain to his chest.
