A member of the singer 's security personnel toldCNN there was no physical contact . `` The neighbor went onto Justin 's property . They exchanged words . The neighbor has had issues before , '' the source said . Investigators are also looking into the neighbor 's complaint that Bieber drove his sports car at high speeds through the otherwise quiet streets of his gated Calabasas , California , community , Whitmore said . Bieber had just returned to his California home Tuesday morning after performing in Europe . Bieber , 19 , moved into a $ 6.5 million mansion in The Oaks of Calabasas a year ago . The exclusive community is also home to Michael Jackson 's mother and his three children . The teen pop star went through similar brush with the law last May when a photographer filed a complaint with the sheriff accusing Bieber of misdemeanor battery .

The photographer said Bieber attacked him as he was taking photos of Bieber and his then-girlfriend , Selena Gomez . Prosecutors declined to pursue the charge against Bieber in the case .
