A Scarborough lifeguard was dragged five to six feet underwater by a shark before he was able to break free on Saturday, amid a growing number of recent great white sightings in the area. A witness reported seeing the torpedo subsequently come out of the water shortly after the lifeguard began fleeing. The incident is consistent with the recent increase in shark activity in the area. Beachgoers are urged to avoid swimming near fish, seals, or areas where birds are feeding, avoid swimming alone, and report shark activity to lifeguards. The Scarborough Police Department also reminded swimmers that shark activity can occur close to the shore and in shallow water.
