Police investigate 2 sex assaults in city parks

Toronto police are investigating two separate sexual assaults that took place in city parks on Sunday.

At around 8:30 p.m. on Sunday, a man sexually assaulted a woman while she was jogging in High Park.

Police had a large section of the park blocked off Monday as they conducted their investigation, CBC's Trevor Dunn reported from the scene.

The victim was jogging in the north end of the park, near the main entrance on Bloor Street. The woman says a man approached her as she rested on a bench. He tried to start a conversation, then sexually assaulted her from behind.

The suspect is described as a black man in his mid-20s with a light complexion, between five foot six and five foot eight, with short black hair.

Joggers in the park told Dunn Monday they are surprised because they use the park often and feel safe there.

Officers could be seen at the park Monday, both patrolling the area and looking for evidence pertaining to the attack.

Sex assault in dog park

Meanwhile, another woman was assaulted Sunday at about 9:30 a.m. at a dog park near Finch Avenue and Don Mills Road, this time at gunpoint.

A man forced a 20-year-old woman into a secluded area with a handgun pointed into her rib cage, police say. She was assaulted, sexually assaulted and treated in hospital for non life-threatening injuries, say police.

The man fled on foot in a westerly direction. The suspect is described as black, between 20 and 30, with braided hair and tattoos on both arms. He was last seen wearing a black T-shirt.

Police don’t believe the two assaults are connected.

While police say that the number of reported sexual assaults is down more than 10 per cent so far this year, there has been a spike in the number of assaults in recent weeks.

"All officers of the sex-crime unit have been busy the last couple weeks and I can’t explain it," said Det. Mark Benallick.
