A York Regional Police traffic cop was left red faced Sunday morning after his SUV rear-ended the very car he had just pulled over.

The incident occurred just after 6 p.m. on Esna Park Drive, just before Woodbine Avenue in Markham.

It was caught on another driver's rear-facing camera as he passed the intersection.

The video shows the officer getting out of his vehicle and approaching the motorist's window before the police vehicle begins slowly rolling forward.

Moments before it collides with the car in front, the officer desperately tries to stop his marked SUV from rolling.

York Regional Police Const. Andy Pattenden said an investigation by the officer's road sergeant, which occurs after each crash, found the officer forgot to put his vehicle in park.

Although Const. Pattenden said he is sure the motorist did not receive a traffic ticket and there were no injuries or visible damage, he said he's unaware if there will be an insurance claim.
