Police searched teen pop star Justin Bieber's California home on Tuesday in a vandalism investigation, and while the Canadian singer was neither arrested nor exonerated, a man at the house was arrested for drug possession, the Los Angeles County Sheriff said.

Detectives raided Bieber's home early on Tuesday after the "Boyfriend" singer was accused of pelting his neighbor's home with eggs on January 9.

Bieber, 19, was detained at his Calabasas home, about 30 miles (48 kilometers) northwest of Los Angeles during the search.

"He has not been arrested nor has been exonerated," Sheriff's Lt. David Thompson said at a news conference following the search.

"We were looking at things that would put him or anything else at the scene," Thompson added.

A unnamed person in Bieber's home at the time was arrested for narcotics possession when deputies found cocaine in plain view, Thompson said.

The vandalism case is being treated as a felony because it caused "thousands and thousands of dollars of damage" to the house, sheriff spokesman Steve Whitmore said.

It is not known what triggered the alleged incident between Bieber and his neighbor, but the Canadian-born pop star has had several publicized run-ins with his neighbors.

Last year, Bieber was accused of speeding through the neighborhood in a Ferrari sports car and also spitting on his neighbor during a confrontation over parties at the singer's home. Prosecutors did not bring charges against Bieber in either case.
