Kristy Swanson pressed assault charges on Sunday against the ex-wife of her companion and former skating partner, Lloyd Eisler, the actress’ representative said.

Police took pictures of bruises on her back and other parts of her body to document the injuries that Swanson claimed she got during a scuffle with Eisler’s ex-wife, Marcia O’Brien, on Friday in Canada, according to Swanson spokesman Michael Sands.

O’Brien filed a complaint against Swanson first, however. Swanson told People magazine she was arrested Saturday night for allegedly assaulting O’Brien. Swanson, 37, said she was released after posting bail in Kingston, Ontario.

“I had to go the police station where I had an appointment at 9 p.m. to begin the process of being arrested,” People quoted her saying on its Web site Sunday.

Sands said Eisler and Swanson were in Kingston to visit Eisler’s children and discuss custody with O’Brien.

Kingston Police Sgt. Rick LaBrash declined comment. Attempts to reach O’Brien were not successful.

Eisler, 44, a former world champion pairs skater, and Swanson met in 2006 while filming the FOX reality series “Skating with Celebrities.” Eisler left his wife for Swanson, whose film credits include “Buffy the Vampire Slayer” and “Ferris Bueller’s Day Off.”
