MICHIGAN CITY, Ind. -- A 12-year-old girl suffered serious wounds caused by a dog early Friday morning.

Michigan City Police were called to the Dunewood mobile home park on US Highway 212 around 7:40 a.m.

When the officer arrived, he saw neighbors attempting to beat a large dog, approximately weighing 140 pounds, that was attacking a 12-year-old girl.

The child broke free and ran inside a trailer, but the dog followed and continued the attack.

Officer Scott Combs grabbed the bull mastiff, wrestled it to the ground and freed the child.

The dog was locked in an adjoining room while Combs, who is also an EMT, tended to her wounds.

The girl was flown to Riley Children's Hospital in Indianapolis.

An Animal Control officer impounded the animal. It is being held in quarantine.

The dog's owner's name is being withheld while police investigate.
