The province's Special Investigations Unit is probing the circumstances surrounding a fatal hit and run in Scarborough late Wednesday morning.

According to the SIU, a Toronto police officer attempted to stop a white BMW west of the Midland Avenue and Eglinton Avenue East area around 11:30 a.m. The BMW fled the scene, according to a statement from the agency.

SIU spokesperson Jason Gennaro later told reporters that the BMW fled eastbound on Eglinton. A short time later, a construction worker was struck and killed near the intersection of Midland and Eglinton avenues. The victim was cutting concrete in the road when he was struck, Gennaro said.

Gennaro could not say why police had stopped the BMW, or whether a police pursuit was underway when the victim was struck.

Police are looking for the white BMW in connection with the fatality.

Earlier Wednesday, Toronto Police Const. Craig Brister told CBC News an officer also suffered minor injuries. However, when Gennaro updated reporters Wednesday evening, he said the SIU has confirmed no officers involved were injured.

The only information Gennaro could divulge about the man who was killed was that he hails from a community west of Alliston.
