Justin Bieber's buddy Lil Za was arrested this morning at the Beeb's home on suspicion of possessing cocaine, according to TMZ.

Deputies from the L.A. County Sheriff's Dept. said the cocaine was "in plain view" during the raid. Authorities were there with a search warrant, looking for evidence to connect Bieber with last week's egg attack on his neighbor.

Officials told TMZ that Bieber was "not connected" to the cocaine.

Lil Za is a rapper who once lived at Bieber's Calabasas home. The two have been friends for years.

Eleven L.A. County Sheriff's patrol cars descended on Bieber's house Tuesday morning. Police believe Bieber may have surveillance footage of the egg attack and reportedly dismantled Bieber's security system and took the video during the search.
