Pittsburgh police say a 19-year-old man was shot and killed by an officer after the man shot a police dog.

Chief Nate Harper says the officers asked the man to remove his hands from under his clothing. Harper says they then noticed a gun and sent the police dog. Harper says the man fired at the dog, fatally wounding it.

The dog's handler returned fire, hitting the man in the head and killing him.

It happened Tuesday evening just outside the city line in Mount Oliver.

Harper says the officer is on paid administrative leave while Allegheny County police and the district attorney investigate.

Harper says early indications are the officers acted appropriately.
