Justin Bieber's friend was arrested for cocaine possession during a raid at the singer's mansion on Tuesday morning (Jan 14).
Police swooped on the 19-year-old star's home in Calabasas, California, to search for evidence related to the egging of his neighbour's home last week, and have charged his friend, Lil Za with felony possession of the class A drug.
Los Angeles County Sheriff's Department Lieutenant David Thompson told reporters: "The cocaine was in plain view of the deputies when they were looking for other evidence.
"[Justin] was not connected to that cocaine except that gentleman was staying at his residence."
Lil Za - real name Xavier Smith - is an old friend of Justin and is thought to have been living at the 'Change Me' singer's home for months.
Lieutenant Thompson added Justin was cooperative during the raid, but as his lawyer was not present he did not answer "any questions at the time we were there."
He also confirmed security footage had been removed from the star's home as part of their investigation into the egging incident - in which Justin is a suspect - which caused up to $20,000 of damage to the neighbouring property.
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. In the footage the neighbour can be heard shouting, "I see you. I f**king see you!" before a boy, who is allegedly Justin, responds, "F**k you! I got another one for you, actually!"
A source close to the singer says he is very upset at the police raid.
The friend told RadarOnline.com: "He is obviously upset that cops basically had free reign and are going through his personal belongings in his house. Justin has been kept out of the house while the search warrant [was] being executed and watched over by several sheriff's deputies."
