A male skateboarder has died in a hit and run in North York overnight on Monday.

The victim, identified as a 34-year-old man, was found lying in the middle of the eastbound lanes of Sheppard Avenue East in the Bonnington Place and Yonge Street area around 1:15 a.m. with a serious head injury, said Det. Const. Scott Matthews, the lead investigator in the case.

He was riding a motorized skateboard on the roadway when he was struck by the driver of a vehicle travelling in the same direction, explained Matthews of Toronto police's traffic services division.

"The driver stopped, exited the vehicle momentarily, then drove away," Gary Long, a spokesperson for Toronto police, told CBC Toronto on Monday morning.

It's unclear what caused the collision, but Matthews noted there's no indication of an altercation between the driver and skateboarder.

Police shut down a section of the roadway between Doris and Kenneth avenues for five hours while officers from the collision reconstruction unit investigated the scene.

Investigators are searching for a suspect described as a woman believed to be in her 40s with black, shoulder-length hair. She was driving a silver- or grey-coloured Toyota Yaris that is believed to be an older model, Long said.

A child was also reportedly in the back seat of the car at the time, he added.

"This is pretty rare. I've never had a collision involving a motorized skateboard," said Matthews.

Officers are canvassing the area for any security cameras that may have captured the collision. Anyone with information is asked to contact police.
