'Buffy' Star Nicholas Brendon -- Back in Rehab After Bloody Window Smashing Incident

EXCLUSIVE

"Buffy the Vampire Slayer" star Nicholas Brendon has checked himself back into rehab after a bizarre incident where cops found him bleeding in an alley. 

According to law enforcement sources ... Brendon got into an argument on July 3 with a woman at her apartment, smashed a window with his bare hands ... and then bolted. Firefighters responded and found Brendon in an alley, bleeding from the hands.

Brendon was transported to a hospital, but did not get arrested.  He checked himself into rehab 3 days later.

This latest incident and trip to rehab comes on the heels of several bizarre incidents involving Brendon -- including two arrests this year at comic book conventions.
