Just when it looked like he was curbing his bad boy behavior, Justin Bieber has found himself in yet more trouble with the law. The Canadian pop star is currently being investigated by the LAPD for attempted robbery after allegedly stealing a woman's phone.

According to TMZ, Justin and his entourage got into an altercation with a group of men at Sherman Oaks Castle Park -- a complex with miniature golf and a batting cage -- Monday night (May 12) when the singer noticed a woman reaching for her phone, presumably to take pictures.

Justin then confronted the woman, who says he reached into her purse and snatched her phone, demanding her to delete any photos she may have taken. Justin eventually returned the phone when he realized there were no pictures, but was said to have acted aggressively towards the woman and her 13-year-old daughter.

Ironically, a photo of Justin with a Castle Park security guard surfaced online from another source. While police took a report from the woman Tuesday night (May 13), Bieber has yet to be taken in for questioning. We'll update the story with more details as they become available.
