A police officer and a suspect were wounded late Tuesday night in an exchange of gunfire outside a Pittsburg home, authorities said.

According to Pittsburg police Lt. Ron Raman, the incident began around 11:30 p.m. as officers approached a suspect outside a home at Maple Street near East 12th street.

“As they attempted to approach the suspect, he fled on foot,” Raman said. “Our officers gave chase. As they were chasing the suspect, he turned and fired upon our officers, striking one of them. Both officers were able to return fire, striking the suspect.”

Raman said the officer was treated and released from a local hospital while the suspect was in stable condition.

Authorities said the suspect was a 30-year-old Oakley resident with an extensive criminal past and was wanted on warrants for gun and drug possession.

The two veteran officers involved in the shooting were placed on administrative leave while the shooting was being investigated by the Contra Costa County District Attorney’s Office.
