Detectives have searched Justin Bieber's home looking for surveillance footage that might serve as evidence the pop star was involved in an egg-tossing vandalism case that allegedly caused thousands of pounds in damage to a neighbour's home.
About a dozen investigators searched the property in Los Angeles and arrested a member of the singer's entourage - Lil Za, a rapper whose real name is Xavier Smith - on suspicion of cocaine possession.
Police lieutenant David Thompson said the cocaine was in plain view in Justin's house when deputies arrived.
Justin, 19, was at home and cooperated with authorities but was not interviewed by detectives. Lt Thompson said he expected the singer to speak with detectives when his lawyer could be present.
"He has not been arrested, nor has he been exonerated," Lt Thompson said of Justin.
Lt Thompson declined to describe what evidence detectives took from Justin's home.
He said the house Justin allegedly egged had custom wood and other expensive features and that several thousands of pounds of damage occurred.
Previous investigations into Justin's conduct by the sheriff's department against the Boyfriend singer have not resulted in charges.
In October, prosecutors declined to charge Justin after a neighbour complained he drove recklessly through the area. Prosecutors in November 2012 also declined to charge the singer after a paparazzo accused him of punching and hitting him after leaving a cinema.
Jail records show Smith, 20, was being held in lieu of 20,000 dollars' bail.
