Officers had been called to the 6700 block of South Morgan Street around 2:15 a.m. to investigate a report of shots fired, according to a preliminary release from police.
Officers saw a vehicle leaving the area quickly, and when they followed it, the driver took off on foot with a gun in his hand, police said. There were a total of three people in the car at the time, said Pat Camden, a spokesman for the Fraternal Order of Police.
An officer ran after him into an alley, and when the man turned towards the officer, the officer shot him, police said.
Neighbors reported hearing two bursts of gunfire. No officers were injured, police said.
The man was taken to Stroger Hospital with injuries that were not believed to be life-threatening, Camden said. Police said he had been talking with paramedics as he was loaded into an ambulance.
More than a dozen police vehicles responded to the shooting. Police said they had found a weapon at the scene.
As detectives searched the alley for evidence, neighbors lingered on patios and looked out from windows of tan brick townhouses.
Standing across the street, 26-year-old Philip Brown said the shooting saddened him.
A lifelong Englewood resident who runs his own promotion and entertainment company, Brown said violence is stifling a neighborhood with a lot to offer.
"There's so much talent in this area," he said. "It's a shame it's getting wasted by this."
