Los Angeles County prosecutors are reviewing an altercation between pop star and a paparazzi person at a Calabasas, California shopping mall. 

They will determine whether criminal charges should be filed against the 'Boyfriend' singer, a spokeswoman has confirmed.

Detectives have been investigating claims by the man who is believed to be the victim that Bieber struck, after he took photographs of him and girlfriend Selena Gomez at the Commons at Calabasas Shopping Centre in last month.

The photographer complained of pain and was taken by the Los Angeles County Fire Department to a hospital, where he was treated and released, officials said.

The LA County district attorney's office received the case Tuesday, and it's unclear how long it will take to make a decision about charges.

The teenager has not commented on the incident which could see him charged with misdemeanour battery for the May 27 incident.

At the time of the physical altercation, the photographer called the police, but Bieber and Gomez were gone by the time they arrived.

Apparently the LA County Sheriff's deputies tried to reach Justin to discuss the incident, but never spoke to him.

The young star was out of America for several weeks on a promotional tour.
