Sex trade workers in Ottawa should be on alert after two similar attacks that began in Vanier, police warned Wednesday.

In both instances, on Dec. 27 and Feb. 3, women who agreed to meet an unknown man in Vanier were taken to another location, then physically and sexually assaulted, Ottawa police said.

Police do not believe these cases are linked to a suspected serial sexual predator. In January, police confirmed that three sexual assaults between Aug. 2012 and Oct. 2013 were linked to the same unknown suspect through DNA evidence, and that seven other cases could be linked, as well. Two sketches of the suspect were released.

Ottawa Staff Sgt. Angela McDade said that the man suspected in the Dec. 27 and Feb. 3 sexual assaults does not fit the same description as the suspected serial sexual predator.

Police are hoping to identify the suspect, described as a white man in his 40s, with a husky build, shoulder length grey or white hair and a short grey or white beard. 

He was wearing black running shoes and a dark hooded sweatshirt pulled over a baseball cap on Feb. 3 when he met a woman near Montreal Road and Marier Avenue around 1 a.m., police said. The man led the woman to a home on Marquette Street near Ste. Monique Street, where she was hit with an object, threatened and sexually assaulted, police said.

A suspect of the same description picked a woman up in an older model green four-door vehicle on McArthur Avenue on Dec. 27, police said. The man drove the woman to an unknown location and led her to a wooded area where he choked and sexually assaulted her, police said.
