A woman has been arrested on suspicion that she tied up a man during sex, then stabbed him repeatedly with a knife and told him she likes to drink blood, police said.
Tiffany Sutton, 23, was arrested on suspicion of aggravated assault on Tuesday night at a Tempe home where she and the victim were living, according to authorities.
The man, whose identity was not released, told police he had consented to being tied up but became scared when the woman attacked him with a knife.
He eventually freed himself and ran away, but Sutton chased him with a pickax, police said.
The man was taken in an ambulance to a local hospital, where he was treated for injuries.
Police said both Sutton and the man admitted that they had consumed alcohol and drugs prior to the incident.
Sutton claimed the entire encounter was consensual, police said.
