LOS ANGELES — Justin Bieber’s squeaky-clean image has finally been smeared. The 18-year-old pop prince is wanted by the LA Country Sherriff’s Department for questioning after he allegedly became involved in a scuffle with a paparazzi photographer. According to the police report filed by the snapper, Justin took offense to his photo being taken while he was hanging out with his girlfriend Selena Gomez in a shopping mall near his house in Calabasas, Calif. The pair came out of a movie theater and were confronted by a large group of photographers. One of them came too close to Selena for Justin’s liking, and, according to witnesses, Bieber hollered at him, chased him down and punched him, leaving a shoe behind in the process. The pap was examined for injuries to his torso, but soon released. — Agencies
