The former Buffy the Vampire Slayer star was taken into custody in Palm Springs, California, on Oct. 11, as the result of an alleged domestic dispute between the actor and an unnamed woman, who is believed to be his girlfriend.
Brendon -- who played Xander Harris on the popular teen dramedy vampire series from 1997 to 2003 -- was arrested on charges of domestic violence and violating a protective order.
Sgt. William Hutchinson of the Palm Springs Police Department tells ET that the incident in question happened around 9 p.m. at the Saguaro Hotel.
Police tell ET that the woman has two other protective orders against Brendon in both New York and Florida. The order allows Brendon to be near the woman, but prohibits him from threatening, harassing, injuring or assaulting her.
Brendon was released from custody on Oct. 12 on a $50,000 bail bond, according to booking records. He is scheduled to appear in court on Nov. 28.
ET reached out to Brendon's rep, who had no comment.
