Former Governor Eliot Spitzer has been accused by a Russian woman of choking her and tossing her to the ground.
Police were sent to a hotel after the woman called 911 saying she cut her wrist.
Spitzer answered the door saying there was no problem.
Officers later returned to find broken glass and blood-stained clothes in the hotel room.
After the woman was taken to a hospital, she told staff there that it was Spitzer who attacked her after she said she was returning to Russia.
A spokeswoman for the ex-governor says the allegation is not true.
Spitzer resigned as Governor in 2008 in the wake a prostitution scandal.
