A 70-year-old Whitehorse woman was struck in the face by a cyclist in Riverdale after she told the man he should be riding in the bicycle lane and not on the sidewalk.

The incident happened Sunday around 2 p.m. near the Macauley Lodge area of Lewes Boulevard.

Carol Boschman says her assailant had startled her by riding his red bicylce past her on the sidewalk. When she told him he should be riding in the bike lane, the cyclist stopped and an argument ensued.

Boschman says he hit her upper body with his fists and on both sides of her face with an open hand.

"He brought up his other hand then and slapped me really, really, really hard on this side, on my left side," she said. "He slapped me three times and I just couldn't believe what was going on."

He threw her to the ground. She yelled for help and the man fled on his bicycle. A witness who saw the assault ran to her and stayed with her until police arrived.

Boschman says the police officer took her to the hospital where one of her arms was put in a sling. She says her upper body is still sore from the attack.

The suspect is described as about 50 years old, five foot ten, with a medium build, and shorter dark hair. He was wearing prescription glasses. He was wearing a red coat with reflective patches on the side, dark pants and a dark hat.
