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 theatre last month, a document obtained Wednesday states.

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

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

Authorities interviewed several witnesses, but none reported seeing Bieber kick the man, and they noted that the photographer kept taking photos as the two singers left the location, according to the document prepared by the district attorney's office.

"All the photos and video taken during this incident by the many photographers were obtained and reviewed," the document states. "There are no photos of a physical altercation."

The case was rejected on Oct. 22 and first reported Wednesday by celebrity website TMZ.
