Kristy Swanson, "Buffy -The Vampire Slayer" was arrested Saturday night for assaulting the ex-wife of Lloyd Eisler, Marcia O’Brien.

Skating with Celebrities star Kristy Swanson was arrested late Saturday night for allegedly assaulting the ex-wife of her companion and former skating partner, Lloyd Eisler, Swanson tells PEOPLE.

“I had to go the police station where I had an appointment at 9 p.m. to begin the process of being arrested,” she confirms.

Swanson was released on $500 (Canadian) bail. Officers escorted her into the police station in Kingston, Ontario, after Eisler’s ex, Marcia O’Brien, filed a complaint against Swanson.

Swanson, 37, claims she was attacked by O’Brien in front of Eisler and O’Brien’s children. The actress’s rep, Michael Sands, says Swanson plans to press charges against O’Brien, saying that police took photographs of her back and other parts of her upper extremities to document the injuries.
