A motorcyclist and a pedestrian are in Sunnybrook Hospital tonight after an incident of pure mayhem at the corner of Yonge St. and Pleasant Blvd this evening. It happened about 5.30 p.m. as three motorcycles were seen speeding north on Yonge from Rosehill Ave. A motorist who saw the motorcycles weaving in and out of traffic said he knew they were “an accident about to happen.” His perception was all too accurate. One of the lane-changing bikes was clipped by a southbound BMW (photo centre) turning left at Pleasant. Police speculate the 75-year-old driver had no idea that the motorcycle would appear out of nowhere in front of his car. The motorcycle was hurled onto the east sidewalk of Yonge Street (photo top) where it injured a woman pedestrian. She is 67 ears old.. The cyclist, aged 29, was also badly hurt. Police said one of the other motorcycles stopped but the third fled the scene. The intersection is one block south of Yonge and St.Clair. Yonge is closed between St. Clair and Rosehill. A woman who witnessed the accident (photo bottom) said the motorcycle seemed to fly to pieces. It landed many feet north of the rider and the pedestrian. She and her friend ran to try to assist the bleeding pedestrian. She is reported to have head injuries. The rider appeared to have broken legs this witness said. Other witnesses said they think the motorcycles were traveling at “twice the speed limit.”
