Police have charged a Toronto man with attempted murder for allegedly hitting a 60-year-old cyclist with an object in North York on Friday, knocking him off his bike and leaving him with life-threatening injuries.

The cyclist was riding his bike in the area of Yonge St. and Wedgewood Dr. around 11:45 p.m. when someone hit him with an object witnesses described as a golf club, Toronto police Const. Allyson Douglas-Cook said.

The impact caused the cyclist to fall off his bike. He suffered life-threatening injuries and was rushed to hospital, where he remains in critical condition.

The suspect fled on foot, police said.

He was later tracked down and arrested.

Sang Hyun Jun, 40, has been charged with attempted murder. He appeared in court at Old City Hall on Sunday morning.

Police do not know the motive behind the attack, but say they have found no evidence that the pair knew each other.

“Unfortunately, given the circumstances, the victim obviously is not in a conscious state to give his info,” Douglas-Cook said, adding “there’s nothing at this point that leads us to believe that they may have known each other.”

Police are looking for anyone with information or dash-cam footage of the incident to come forward.
