Cocaine was found in Justin Bieber’s mansion after it has been raided by police on Tuesday, January 14, 2014 over his alleged egging of a neighbour’s house.

Eleven police cars arrived at the “Heartbreaker” singer’s mansion in Calabasas, California, armed with a search warrant and a battering ram after the owner of a house next door complained of damage which could total up to $20,000 caused by eggs thrown at it last week.

Los Angeles County Sheriff’s Department spokesperson Steve Whitmore told the New York Daily News newspaper: “I can confirm we have served a search warrant at Justin Bieber’s residence as part of a felony vandalism investigation. He is there, and we are right now in the process of serving the warrant. We’re looking for anything we might need to move this investigation forward.”

Officials believe surveillance video in the singer’s home could have also caught the incident on tape, and help catch the culprit.

The crime is being treated as a felony because over $400 of damage was done to the neighbour’s property. This means, if convicted, Justin, 19, could potentially face jail time.

The damage is estimated to be so high because the entire front of the damaged property needs to be repaired with expensive Venetian plaster and the doors re-stained.

The neighbour claims he saw Justin from his second-floor balcony and videotaped some of their verbal exchange.

Justin Bieber’s friend, Lil Za was arrested for cocaine possession during a raid at the singer’s mansion. Real name Xavier Smith, he is an old friend of Justin and is thought to have been living at the singer’s home for months.
