The Buffy the Vampire Slayer actor was arrested in Saratoga Springs, New York on Wednesday when he apparently choked his girlfriend after a fight, according to officials.
"Last night around 11:30 p.m., we got called to a nice family-owned hotel in town for a reported domestic disturbance," Bob Jillson, Investigations Lieutenant at Saratoga Springs Police Department, tells PEOPLE. "We got to the room and we found a 33-year-old female there by herself, and she reported that she had been in a domestic incident with Nick, and he had subsequently left before we got there. She did not have any physical injuries that we were aware of."

"He was placed under arrest without any incident," says Jillson.
Brendon, 44, spent the night in jail and was charged with two counts of criminal mischief and one count of obstruction of breathing, which are misdemeanors. He was also charged with robbery in the third degree, which is a felony.
The arrest is the latest in a series of difficult incidents for Brendon this year. The police have been called to Brendon's home on two occasions in recent days, for unspecified mental health issues.
Brendon was previously arrested three times this year and in June entered rehab for substance abuse, depression and alcoholism.
On Aug. 26, the troubled actor taped a segment on Dr. Phil, where he was to discuss his mental health and addiction issues, but he was quick to walk off set during the taping when he did not appreciate the questioning during his interview.
"My illnesses and addictions are a daily struggle for me, and I am committed to working on them for the rest of my life," Brendon wrote on his Facebook page after walking out of the taping. "A big part of that is focusing on positivity. I’m the first to admit I’ve messed up, a lot, and I’ve hurt people I care about and who care about me."
Brendon is best known for playing Xander on Buffy the Vampire Slayer from 1996 to 2003. He split from his wife, Moonda Tee in February.
