The Los Angeles County Sheriff's Department are reportedly ''absolutely furious'' that Justin Bieber won't face felony charges for egging his neighbour's house.

The 20-year-old singer was accused of causing $20,000 in damage to Jeffrey Schwartz's house within the exclusive gated community The Oaks in Calabasas, California in January, but he will only be charged with misdemeanour vandalism in connection with the incident.

A source told gossip website that detectives investigating the case are furious with the LA District Attorney (D.A.) for refusing to consider more severe charges against the 'Confident' hitmaker, despite their recommendations.

The law enforcement insider said: ''He caused $20,000 in damage and there is just no denying that.

''It sends the wrong the message to the community that celebrities are treated differently. This case should be filed against Justin as a felony, period.''

But another source said: ''There just isn't enough compelling evidence to file a felony vandalism charge against Justin. Many feel the Los Angeles County Sheriff's Department/Lost Hills Station has been extremely over-zealous in their investigation involving Justin, such as sending over a dozen squad cars to execute a search warrant at his house, and issuing press releases when the investigation was handed over to the D.A. It's just not done to the average guy.

''The estimates for repair of $20,000 to the neighbour's house are just overblown. Yes there was some minor damage, but nowhere near that amount.''

The 'Believe' singer moved the last of his belongings out of the house this week after recently selling the property to Khloe Kardashian.

Justin is now renting a house in Atlanta, Georgia, with a view to buying a property and moving to the city full time.
