He took a bite out of crime.
A Florida K-9 tracked down a fleeing car thief to a backyard last month and secured an arrest by biting down on his buttocks, officials said Monday.
The Marion County Sheriff’s Office was alerted to a stolen vehicle last last month in Ocala and dispatched a deputy and his police dog, Jax, to investigate.
Video shows the officer spotting Matthew Gebert, 29, in the stolen SUV and tailing him for several blocks as he begins to pick up speed and drive evasively.

The officer then activates his lights and sirens, causing Gebert to hit the gas in an attempt to flee.
The deputy pursues Gerbert at high speeds in residential areas for several minutes as he runs red lights and stop signs before finally abandoning the car and taking off on foot, the clip shows.
The footage shows Jax sprinting after Gerbert, finding him in a backyard and then ripping away at his rump while the deputy makes the collar.

“The sooner you show me your hands the sooner I take the dog off!” the officer yells as Gebert screams from posterior pain.
“Get him off!” he yelps. “Please!”
Gebert was arrested and found in possession of cocaine and drug paraphernalia.
He was hit with raps including grand theft, fleeing cops, drug possession, and violating probation and was held without bail.
