An officer witnessed a person hit an ambulance and attempt to flee the scene on foot, eventually leading to an arrest.

An off-duty Ottawa police officer is being credited for tracking down a hit and run driver over the weekend.

According to inspector Francois D'Aoust, the officer witnessed a car hit an ambulance in the Walkley Road and Don Reid Drive area, Sunday.

The man allegedly started to flee on foot when the off-duty officer began to give chase.

Eventually the officer was able to catch and arrest a 56-year-old man.

He's since been charged with failing to remain at the scene of a crash.

There were no injuries reported in the crash.
