A woman in Russia's central Nizhny Novgorod Region helped to catch a man who raped her by biting his penis.
The woman was raped in January 2011 in the grounds of the Dzerzhinsk Municipal Children's Hospital.
According to investigators, the suspect raped the victim and then threatened to kill her.
The woman bit the man so hard that he had to go to hospital.
The suspect was arrested in January, after police investigators had warned local hospitals that a man could turn up with an injury to his penis.
He could face up to ten years in prison if convicted.
