A deputy sheriff was attacked with a box cutter at a highway rest stop in Mississippi, and officials say his K-9 partner came to his rescue.

Hancock County Chief Deputy Don Bass says assailants beat and cut Todd Frazier when he stopped to check on a parked car Monday in Pearlington, near the Gulf Coast bordering Louisiana.

Bass says Frazier managed to release his dog, a black Belgian Malinois named Lucas, from the patrol car during the attack. Lucas then attacked the men who had gone after Frazier. Bass says the dog broke some teeth and suffered scrapes and cuts from being dragged around the pavement but was able to save the day.

Frazier is at home recovering, and Lucas is being treated with medication.

No one has been arrested.
