LOS ANGELES (AP) — Justin Bieber won't face criminal charges for allegedly threatening a neighbor who complained about his driving.

City News Service says Los Angeles County prosecutors decided Wednesday that there's insufficient evidence to charge the pop star.

A neighbor in Bieber's gated Calabasas neighborhood told a sheriff's deputy that Bieber threatened him and spat in his direction when he confronted the 19-year-old about his driving last March.

Prosecutor Alan Yochelson wrote in a document that Bieber's response seemed "immature" but not necessarily criminal.

He also said there's not enough evidence to charge Bieber over a neighbor's complaint that Bieber drove his Ferrari recklessly through the area in May. Yochelson said it's unclear who was at the wheel.
