BREAKING NEWS - Justin Bieber Being Investigated For Battery

After returning from Europe for a quick break from his "Believe" tour, Justin Bieber was quick to get himself in trouble after touching down in L.A. The pop star was accused of battery by a neighbor Tuesday morning, according to Los Angeles County Sheriff's spokesman Steve Whitmore, who says police are investigating the incident.

Bieber flew out of Poland last night following his concert in Lodz, and he arrived home early on Tuesday. A source close to Bieber's security team tells X17online that a male neighbor came on to his Calabasas property, but "there was no physical altercation."

The man began screaming at Bieber about throwing loud parties, according to TMZ, but the website later noted that it wasn't a noise complaint over all-night ragers, but rather Bieber's Ferrari. Bieber reportedly had the car delivered to his home last night on a flatbed truck and was "racing the vehicle up and down the streets" this morning. The neighbor was apparently upset about the noise and felt the 19-year-old star was "endangering the community by tearing through the streets at breakneck speeds."

Whitmore said that the accuser told deputies Bieber "threatened" and "made physical contact with him" and has filed a battery report. We're guessing Bieber had plenty of witnesses and cameras, so if he's telling the truth, authorities should be able to clear this up pretty quickly...
