LOS ANGELES - Prosecutors say they won't file charges against Justin Bieber over a May confrontation with a photographer because of a lack of corroborating evidence.

A document obtained Wednesday states that three Los Angeles County sheriff's investigators found no visible injuries, video or photographs to confirm the photographer's story that Bieber kicked and punched him.

Prosecutors had been asked by police to consider filing a misdemeanour battery charge against the pop star.

Bieber was leaving a movie theatre with girlfriend Selena Gomez when he got into a scuffle with a photographer in the parking lot.

The photographer claimed Bieber kicked him in the abdomen and punched him.

The case was rejected in October and was first reported Wednesday by celebrity website TMZ.
