Police noted that Bieber, his security and entourage co-operated fully, but did not make an official statement.
The singer "has not been arrested, nor exonerated" in the felony vandalism incident, Lt. Dave Thompson told media at a midday press conference.
"I get it was done with eggs, which makes you feel it is a lower-level crime, but a felony crime is a felony crime, no matter how you commit it. It rose to the felony section and the judge signed a search warrant to go and get evidence," he said.
"There's an extensive level of damage. I and the sheriff take this seriously," he added. "We didn't do the search warrant to send a message. That's not what we do."
Officers did, however, arrest one of the "seven or eight" people present at the singer's house for possession of cocaine, which was in plain view. An unnamed, adult man who had stayed over at Bieber's residence was arrested for felony narcotics possession, Thompson said.
Vandalism over $400 US
The Stratford, Ont.-born singer is under investigation for allegedly hurling eggs at a neighbour's home, at approximately 7:30 p.m. local time last Thursday.
Authorities said the case is being considered a felony because the damage to the neighbour's home exceeded $400 US. Thompson said the damage was in the "thousands of dollars" and encompassed "the entire front exterior of the house."
The singer lives in a gated community in Calabasas, a celebrity enclave northwest of downtown Los Angeles.
Questioned about the large police contingent that arrived at the singer's home today, Thompson confirmed that nearly a dozen detectives were present to enact the search warrant.
"In these types of situations, we don't know what we are going to confront.... We don't know who's staying at the house or who might be under the influence of anything," he said.
"It's always good to err on the side of safety."
In the past year, both on tour and while at home, Bieber has been involved in a host of "bad boy" incidents. However, previous police investigations into his conduct have not led to charges. In October, for instance, prosecutors did not charge him after a neighbour complained he drove recklessly through the area.
In November 2012, prosecutors also declined to charge the singer after a paparazzo accused him of punching and hitting him after leaving a Calabasas movie theatre.Suggest a correction
