A would-be rapist was arrested for sexual assault after he mistakenly called police instead of an ambulance to get treatment for a bite wound inflicted by his victim, it was learned Thursday.

Kanagawa Prefectural Police said Hirokazu Okada, 29, attacked a 26-year-old woman from Higashi Yamato, Tokyo, on a street in Tsuzuki Ward here at around 12:30 a.m. Sunday in an attempt to rape her.

While trying to kiss her, she bit him in the upper lip, causing him to flee the scene on foot, they said.

Bleeding heavily, Okada tried to call an ambulance, but mistakenly dialed 110, the police number, instead of 119. Police then called an ambulance to the scene.

Okada claimed he was bitten by a dog, but the woman called police to report the assault -- and the bite.

Okada was apprehended on suspicion of sexual assault after leaving the hospital. The woman suffered injuries to her right leg when she was pushed to the ground.

Police said the suspect admitted the attack, quoting him as saying, "I panicked and mistakenly called police."
