The incident involved the 26-year-old "High School Musical" star and a man Efron identified as his bodyguard. Reportedly, the bodyguard, who said he and Efron were tooling around downtown Los Angeles on Sunday at 12:30 a.m. when the car ran out of fuel. It rolled to a stop at the bottom of a downtown L.A. off-ramp. Efron said that while they were waiting for a tow truck they threw a bottle out the window -- it was not clear was in the bottle -- and it hit the pavement near a group of transients.
That angered the transients, who confronted the pair, believing they intentionally threw the bottle at them.
The bodyguard -- who wished to remain unnamed -- said that the went after him with a shank, stabbing him in the face, stomach and chest. Efron exited the car and a vodka bottle at the transients to fend off the attack. The bodyguard said that Efron beat off the attack and saved his life.
The mention of the bottle was strange though, unless Efron and crew had more than one empty bottle in the car.
There were no arrests, as police viewed the incident as "mutual combat." TMZ's source claimed Efron was "obviously intoxicated" at the time of the events.
