Buffy The Vampire star Nicholas Brendon, who was arrested in March for attacking a police officer, has just checked himself into rehab for alcohol and sleeping pill addiction.

Nicholas claimed after his arrest that he had blacked out and didn’t remember the incident. He was charged with felony vandalism and was released on bail.

He’s now being treated at the SOBA Recovery Center in Malibu. This is Nicholas’ second attempt at rehab. He did his first stint in 2005, but relapsed shortly after.
