A Little Rock police K-9 officer escaped from its pen in Saline County and bit two people, authorities said.
At least one of the victims was reportedly taken to a local hospital for treatment.
The Little Rock police department said the dog Ammo, who has been with the department for three years, got out Monday, jumped a six-foot privacy fence and then went across the street, where it bit two neighbors.
It happened at Little Rock officer Jason Harris' home in Saline County. Police K-9 officers typically live with their human officer handler.
According to a Saline County sheriff's office report, a 35-year-old neighbor told officials he was doing yard work when he "noticed a dog pacing in his yard."
The man attempted to grab the dog's collar to see who its owner was, the report said, but it showed its teeth and the man backed away. The dog then bit him on the leg.
A 73-year-old man was also bitten, but details on how that bite occurred weren't included in the report. He was taken to CHI St. Vincent Infirmary in Little Rock before authorities arrived.
The Little Rock agency said Ammo is back home but "cannot report to work for 10 days under [the] Saline County vicious dog ordinance." Police said the officer was not home when Ammo escaped.
Ammo, a Dutch Shepard, was found in the home's driveway.
