A police officer in Texas begged and pleaded with a man to drop a knife … saying she didn’t want to shoot him — and, the moment was captured on harrowing body cam footage.

The video — released Saturday — captured the officer-involved shooting from February … when a San Antonio police officer arrived at a park where a man was climbing out of a car that crashed into the lake.

It’s unclear exactly how the car ended up in the lake … but, the man — later identified as 30-year-old Chase Deckard-Thomas — hops out of the car with little issues.

In the clip, the officer asks the man if he’s alright … before noticing he’s got what looks like a knife in his pocket and pulls out her gun.

The officer asks him repeatedly to drop the knife — screaming at the top of her lungs that she doesn’t want to shoot him. However, Deckard-Thomas keeps coming … and, eventually she shoots him.

Local reports say the man was transported to a local hospital where he was treated for life-threatening injuries. He survived and has been charged with aggravated assault against a police officer.
