Justin Bieber is under investigation by the Los Angeles Police Dept. in connection with an alleged robbery after an altercation with a mother at a miniature golf course in Sherman Oaks, Calif. Monday evening.

The Canadian singer is accused of reaching into the woman's purse and swiping her cell phone, as police told Breaking Celebrity News that “a victim filed a report involving an incident on Monday night at 10:30 p.m.,” and that detectives are getting a statement from the accuser, who was with her 13-year-old daughter during the incident.

The 20-year-old — who was in Oklahoma City Tuesday to watch the Clippers-Thunder playoff game — “hasn't been arrested or questioned,” officials told Breaking Celebrity News.

According to reports, the Biebs was at Castle Park, a miniature golf and bating cage complex, when the alleged victim noticed him in the batting cages and began taking pictures with her cell phone.

Bieber took notice of the amateur shutterbug and demanded to she erase the pictures from the camera, according to online reports.
