Tempe police arrested a woman Tuesday night 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.
Tiffany Sutton, 23, was arrested on suspicion of aggravated assault at 11:55 p.m. in the 1000 block of South Lola Lane, where she and the victim were living, police said.
The man 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 were unsure if the pair were friends, but Sgt. Mike Horn said the man and woman were not in a relationship.
Both admitted to authorities that they had consumed alcohol and drugs prior to the attack, Horn said.
The man called his friend, who found him passed out and then called police. Sutton initially acted like she was the victim, Horn said.
Sutton later told police the entire encounter was consensual.
