A Florida woman has been charged with battery after she attacked an elderly man in a wheelchair, claiming to be a vampire, police said.

According to the St. Petersburg police, Milton Ellis, 69, and Josephine Smith, 22, met on the street and went to the porch of a vacant restaurant to get out of the rain. Ellis fell asleep in his motorized wheelchair only to be woken up by Smith who was allegedly on top of him, biting on his face and arms.

Smith, after proclaiming, I'm a vampire. I am going to eat you, began to bite Ellis on his arm and lips leaving him bloody before he managed to escape and call for help, police said. He was later treated with stitches at a local hospital and released, according to a Reuters report.

Police, arriving on the scene, found Smith bloody and half-naked. She couldn't remember what had happened and didn't identify herself as a vampire, St. Petersburg Police spokesman Mike Puetz said.

Smith, who was arrested early Thursday, is currently being held in detention with bail set at $50,000.

Serial killers and similar delusional individuals have killed people, believing themselves to be vampires and in need of blood to drink. In one of the most notorious case of real-life vampirism, Tracey Wigginton, an Australian murderer, also known as The Lesbian Vampire Killer killed a man in 1989, purportedly to drink his blood.

But the vampire subculture repudiates such individuals, stating that they are not real vampires, and that the subculture does not promote violence or crime in any form.
