The damage to the house included the Venetian plaster, which is about $15,000 worth of damage, and the damage to the front entry doors cost $5,000 because they have to be restained. Justin Bieber was confronted about throwing eggs but instead of apologizing he threw more eggs and cursed at his neighbor.
TMZ states that the L.A. County Sheriff's deputies will refer the case to the Los Angeles County district attorney who could file vandalism charges against Bieber. Since the damage is more than $400 he could be charged with a felony.
Justin's neighbor believes at least 20 eggs were thrown at his property. The neighbor's 13 year old daughter called the cops during the egging while Bieber yelled obscenities. There have been previous issues between Justin and his neighbor.
