Police are investigating a strange incident involving two drivers in the downtown core on Tuesday night that resulted in a man clinging to a moving car.

The dramatic altercation between the men was caught on video by a passerby and sent to CTV News Toronto.

A witness said he was leaving a restaurant near Dundas Street East and Sherbourne Street shortly before 10 p.m. when a blue vehicle suddenly sped up to the intersection and cut off a white car.

The man from the blue vehicle approached the white car and reportedly dragged the driver out of his seat in an attempt to take away his car keys.

According to the witness, who wished to remain anonymous, the two drivers exchanged words and the man in the blue car accused the other of sideswiping his car and taking off from the scene.

One of the two men threatened to call police.

As the white car begins to move, the man jumps on to the hood and clings to the hood of the vehicle as it speeds away. The man was dragged about 30 to 40 feet before falling off the car into a live lane of traffic.

Police told CTV Toronto Tuesday that the man suffered only a minor leg injury.

Officers are investigating the circumstances surrounding the incident and are also searching for the driver of the white vehicle.
