Justin Bieber Battery Case Being Sent To Prosecutors

We're told cops have already decided to refer the case to prosecutors, even though the investigation is far from complete. They have requested to interview the Biebs, but he's in Norway now. It's pretty typical for police to refer high-profile cases to prosecutors.

TMZ broke the story ... Bieber's a suspect for allegedly committing criminal battery against a photog in Calabasas Sunday afternoon. The photog called 911 after the scuffle, but by the time cops arrived, the singer had split.

The pap was taken to a nearby hospital in an ambulance. He then filed a police report naming Bieber as the culprit.
