CHICAGO (STMW) — A Chicago Police officer shot and killed a pit bull which attacked other pets Tuesday morning in the Garfield Ridge neighborhood on the Southwest Side.

An officer discharged a weapon at a dog in the 5600 block of South Neenah Avenue at 10 a.m., according to Independent Police Review Authority spokesman Bruce Dean. The agency investigates incidents in which officers discharge a weapon.

The animal was killed, but no one else was injured, News Affairs Officer Veejay Zala said.

At least one pit bull was running loose in the area and it bit another dog, taking “a good chunk” out of a chocolate Labrador that was being walked by its owner, a neighbor said. The man was able to fight off the attacking animal, the neighbor said.

Police were called, and an officer shot and killed the pit bull in the backyard of a residence where the animal was attacking a second dog, the neighbor said.

City Animal Care and Control was called to the scene, but a spokeswoman did not immediately return calls seeking comment.
