Law enforcement officials told TMZ that deputies are looking for any type of evidence that might link the 19-year-old singer to an egg assault that took place at his neighbor's home last Thursday.
Officials will search for other eggs -- that could match the eggs found outside the neighbor's house -- as well as possible video from the incident that might be in the pop star's home.
If found guilty, Bieber could be charged with felony vandalism for the incident.
Last Thursday, one of the singer's neighbors called the cops and claimed the "Boyfriend" singer had caused tens of thousands of dollars worth of damage by throwing eggs at the front of his house.
The victim explained the Venetian plaster on the outside of his Calabasas, Calif. home had been damaged and that it needed to be redone. Any act of vandalism that surpasses $400 worth of damage is considered a felony in the state of California.
You can watch the victim's interaction with the egg thrower in the video below.
