A police officer in Pennsylvania was able to thwart an armed robbery inside a taxi on Monday just by randomly pulling up behind the car when it was stopped at a red light.
The would-be robber, Victor Martinez-Herrera, 18, decided to pull a gun on his taxi driver, Ralph Valletta, after Valletta stopped his car
However the thug didn't realize a police cruiser had just pulled up behind them.
Just as he tries to grab the money from a terrified Valletta, the officer materializes at the side of the car, and realizes what was going on.
The incident was caught on the dash dam inside Valletta's car.
