Justin Bieber is wanted for questioning by Los Angeles County police after an alleged scuffle with a photographer on Sunday (27May12).
The pop superstar reportedly became embroiled in a spat with a snapper outside a shopping centre in Calabasas as the man attempted to take pictures of the singer and his girlfriend Selena Gomez.
A Sheriff's Lieutenant has revealed the photographer dialled 911 and was taken to hospital where he was treated and later released, before filing a police report.
Cops now want to talk to the star about the alleged incident, according to the Los Angeles Times.
Pictures show Bieber having lost a shoe and his baseball cap in the alleged scuffle, while Gomez is seen helping him retrieve the hat and put his sneaker back on.
Bieber has yet to comment on the report, simply writing in a post on his Twitter.com page, "Gonna focus on the important stuff. The music. (New single) Die In Your Arms hits iTunes in less than 24 hours."
The Baby hitmaker is due to fly to Norway this week (beg28May12) to kick off a promotional tour for his new album.
