A woman out for a jog Saturday just north of downtown was tied up with green painter's tape, robbed and sexually assaulted, say police.

This is the third violent sexual assault reported to police on the city's northside since March.

Police said the latest attack happened Saturday at about 6:30 p.m. when a 37-year-old woman who was jogging west on 116th Avenue and 102nd Street, was sexually assaulted and robbed.

"This was pretty brazen, happening in daytime hours," said Det. Brenda Dalziel, of the police sexual assault unit. 

There are similarities to two attacks in March, where the women were also grabbed from behind by a male suspect.

Police are warning the public, again, after the most recent sexual assault.

Police said the suspect in Saturday's attack is alleged to have dragged the woman down a nearby alley, tied her up with green painter's tape and demanded money before assaulting her. The suspect was also carrying a box cutter, say police.

Police said the woman was able to escape from her attacker.

The suspect is described as an aboriginal man about 30 years old, six feet tall and weighing about 160 pounds. He was wearing a black track suit with a white stripe, police say.

On March 3, police responded to an assault call near 101st Street and 128nd Avenue, after a woman said a man dressed in dark clothing approached her from behind, forcing her into an alley.

The man sexually assaulted the woman before fleeing. Police called that assault a violent and serious attack.

The next day, police responded to another assault call in an apartment complex parking lot just two blocks from Saturday's attack. It was reported that a woman was walking through the lot near 118th Avenue and 102nd Street, when a male suspect approached and assaulted her.

"We haven't yet concluded that these incidents were committed by the same individual, though there are certainly some similarities," said Det. Dalziel.

"Regardless if these incidents are related or not, we want the public in this area to be aware and to report any suspicious activities to police," she said.
