Richard Terrance Vrastak, 38, died in hospital about 10:30 a.m. Thursday. Sheldon Mark Yesno, 32, has been charged in relation to the incident and is in police custody.

Police said Vrastak was riding a bicycle on the sidewalk beside a parking lot when he was hit by a minivan on south Algoma Street, near John Street. 

The driver of the minivan fled the scene, but police were able to use surveillance video to help identify the vehicle.

Detective Sergeant Don Lewis said police believe the incident was related to drugs.

"There was information throughout the investigation that there was some type of ... drug transaction that took place prior to the incident itself, before it unfolded on Algoma Street," he said.

Police have alleged the vehicle that struck Vrastak was driven into him deliberately.

Yesno has also been charged with failing to remain at the scene of an accident.

A 37 year old man who was initially charged with dangerous driving in connection with the incident has been released.
