Durham police are hoping new video of a person setting a car on fire will prompt witnesses to come forward.
Police were called to a home on Ritson Dr. in Oshawa around 2 a.m. on July 3.
Officers found a Chevrolet Cruze parked in the driveway of the house fully engulfed in flames.
A second vehicle in the driveway had the front tire clashed as well.
Investigators released video of the incident that appears to show a person approaching the vehicle, pouring an accelerant and then setting it on fire before fleeing on foot.
Anyone with information about this incident is asked to call Det. Cst. Kollaard at 1-888-579-1520, ext. 2738.
