Police officers reportedly found marijuana in Justin Bieber's car.

The 19-year-old star's bodyguard was arrested in Atlanta, Georgia on Tuesday (25.02.14), for allegedly stealing a photographer's camera, and a small amount of the drug was uncovered in the singer's Escalade.

A law enforcement source told gossip website TMZ.com that while officers were searching for the camera in the vehicle, which they retrieved and returned to the paparazzo, they also found less than an ounce of the drug and two large glass smoking pipes, but it was enough to charge anyone with a crime.

The 'Baby' singer's driver said he had no knowledge of what was in the back of the Escalade and usually doesn't ask questions, according to the police report.

The vehicle was towed to police headquarters from a fun house that Justin had rented for the day and inspected.

Justin has been accused of using the drug regularly in the past and pilots flying his private jet last month were reportedly forced to wear oxygen masks because the plane was so thick with marijuana smoke.

The 'Believe' singer, his father Jeremy Bieber and an entourage of 10 flew from Canada to New Jersey on January 31 and allegedly ignored warnings to stop smoking the narcotic, with flight staff forced to take drastic action as inhaling the smoke would have led to them failing drug tests.

The official incident report said: ''The captain of the flight stated that he warned the passengers, including Bieber, on several occasions to stop smoking marijuana.''

Justin's on/off companion Chantal Jeffries, who was with him when he was arrested in Miami last month, claimed on Tuesday that she had never seen him use drugs.
