Justin Bieber paparazzi fight charges droppedGregg DeGuire, WireImage

LOS ANGELES (AP) - Prosecutors decided not to file any charges against Justin Bieber after investigators found no evidence that the pop star had kicked and punched a photographer after leaving a movie theater last month, a document obtained Wednesday states.

Prosecutors had been asked by police to consider filing a misdemeanor battery charge against Bieber, but Los Angeles County sheriff's investigators found no visible injuries, video or photographs to confirm the allegations by the photographer.

Bieber, 18, was leaving the theater in suburban Calabasas with girlfriend Selena Gomez on May 27 when he had the encounter in a parking lot.

A doctor found only superficial injuries, and deputies observed no injuries on the man after the incident, the document states.
