The officers called for a marked squad car, but the suspects took off in the van, and police pursued them for six miles, Camden said.

Finally, around 7:30 p.m. in the 5300 block of West Congress Parkway in the South Austin neighborhood, the van crashed into a marked police vehicle. Then the burglary suspect got out of the van and began running, pointing his handgun at officers chasing him, police said.

Police fired at the suspect, and opened fire a second time after the suspect fled into a gangway, climbed a gate and again pointed the gun at officers, the statement said.

He continued to flee and was arrested a short time later hiding on the roof in the 5300 block of West Harrison Street, police said.

Police News Affairs Officer Ron Gaines confirmed the suspect was shot by police. The suspect suffered a gunshot wound to the ankle and was taken to Loretto Hospital, Camden said.

No. 7 Harrison buses were rerouted in the area because of the police activity, according to the Chicago Transit Authority.

The Independent Police Review Authority, which investigates all police-involved shootings, confirmed an officer fired a weapon.

No police officers were hurt, and officials continue to investigate whether any other suspects were involved with the chase, according to police News Affairs.
