Justin Bieber's bodyguards accused of battery at Hollywood Hookah lounge

Los Angeles authorities have opened another battery case against Justin Bieber's bodyguards, in the same week that his protectors were allegedly involved in a string of incidents in Miami.

TMZ reported Saturday that the 19-year-old singer and his protectors were at a Hollywood hookah lounge when someone approached him to take a photo.

A "scuffle" erupted when one of Bieber's bodyguards tried to stop the person -- apparently not a paparazzo -- from snapping a picture. The police have opened a misdemeanor battery case investigating the incident.

Earlier this week in Miami, Bieber's entourage was implicated in three different altercations over having his picture taken. In one recorded incident, the singer can be heard shouting, "Grab that camera!!! Get that f***ing camera out of here!!!" In another scuffle, one of Bieber's bodyguards was accused of choking a photographer.
