Officials say the call came in as an attempted carjacking. The alleged suspect was shot and is now in very critical condition.
It happened just before 11:30 p.m. Thursday at the intersection of Holme Avenue and Willits Road in Northeast Philadelphia.
Investigators are still gathering details about exactly what happened leading up to when they say the off-duty officer shot the suspect.
The scene is now clear but the intersection was shut down for roughly five hours overnight.
There are two cars involved and at least two shots were fired. At the scene, the off-duty officer's unmarked car could be seen with a shattered driver's side window.
The Action Cam was there as water department crews used machinery to dig in the sewer under the guidance of Philadelphia police detectives.
Action News is still working to get information on how this all played out.
Police have not yet said whether the suspect was possibly armed.
