• The DEA agent was struck during an investigation in the Ashburn neighborhood Sunday afternoon.



About 12:50 p.m. Sunday, police were called to an area near the 8200 block of South Kedzie Avenue, where they found the agent with a head injury and a broken leg.



The agent was working a drug investigation with other officers and stopped a car they believed was transporting cocaine, according to a statement from the DEA's Chicago field division. When they tried to arrest the driver, he took off, hitting the DEA agent, who was on foot.



Authorities fired shots at the car and a suspect was being treated at a hospital, the DEA said. The suspect showed up at the hospital with a gunshot wound and was identified as the owner of the car. He was put into custody, authorities said.



• The other police-involved shooting occurred around 10:45 p.m. Saturday when officers responded to a call of a gang-related disturbance near 47th and Ada streets, according to police Deputy Chief Carlos Velez.



Officers saw a group of people, one of them with a handgun, in the street next to a car that blocked traffic, according to Pat Camden, a spokesman for the Fraternal Order of Police.



Police officers chased the man with the gun. The man, believed to be in his 20s, ran into an alley near 48th and Throop streets. "Partway into the alley, the armed offender turned toward the officer and pointed the gun at him," Velez said.



The police officer shot the man three times, hitting him in the head, according to Velez and Camden.



He was taken in critical condition to Advocate Christ Medical Center, Velez said.
