The Los Angeles Sheriff's Department searched Justin Bieber's home for evidence in an egg-tossing vandalism case involving the pop star.
Bieber was at the home when nearly a dozen deputies served the warrant Tuesday morning and he was being cooperative with investigators, sheriff's spokesman Steve Whitmore said.
Deputies are investigating Bieber, 19, for allegedly throwing eggs at a neighbor's home on Thursday evening and damaging its exterior. The singer lives in a gated community in Calabasas, a celebrity enclave about 30 miles northwest of downtown Los Angeles.
Whitmore said the search warrant is for a possible felony case because the damage to the neighbor's home exceeded $400. A press conference on the case has been scheduled for late Tuesday morning. Authorities have not detailed what evidence they were searching for in Bieber's home.
An email message sent to Bieber's publicist Melissa Victor was not immediately returned.
Previous investigations into Bieber's conduct by the sheriff's department against the "Boyfriend" singer have not resulted in charges.
In October, prosecutors declined to charge Bieber after a neighbor 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 Calabasas movie theater.
