Police took pictures of bruises on her back and other parts of her body to document injuries Swanson claimed she got during a scuffle with Eisler's ex-wife, Marcia O'Brien, on Friday in Canada, said 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 weren't successful.
Eisler, 44, a former world champion pairs skater, and Swanson met in 2006 while filming "Skating With Celebrities," News Corp.'s Fox network reality series. Eisler left his wife for Swanson, whose film credits include "Buffy the Vampire Slayer" and "Ferris Bueller's Day Off."
