Around 2:19 p.m., a 911 caller reported a dog in a yellow dumpster in an alley near the 2000 block of West Jarvis Avenue, between Hoyne and Seeley.
The concerned citizen said several teens, one of them dressed in a dark-colored jacket with fur around the hood, dumped the animal in the dumpster and fled the scene.
When police arrived, an officer observed a "pit pull" covered in blood, wrapped in a garbage bag, inside the dumpster.
The officer said the dog was still alive.
Animal Control was notified.
As of 3 p.m., there were no further updates.
UPDATE: 3:11 p.m. --- Officers removed the dog from the dumpster. Dispatch was instructed to cancel their call to Animal Control. It's unclear if the dog is dead or alive.
