VANCOUVER - RCMP say there has been another sex attack at UBC on the weekend and police have concluded the string of assaults are the work of the same man.

Sgt. Peter Thiessen says a woman who was walking alone on the campus at 1:30 a.m. on Sunday noticed a shadow walking behind her before she was grabbed from behind.

As in the previous cases, the victim flailed her arms and struggled and the suspect ran away.

There have now been six attacks on the campus over the previous weeks and Thiessen says police have put additional resources into solving the case.

UBC officials say they are treating the matter with the utmost urgency and are looking for anyone with tips about the suspect.

The man is described as a Caucasian in his late 20s or early 30s, of slim build and somewhere around six feet tall.

Mounties, UBC, to update probe into recent series of campus sexual assaults

VANCOUVER - RCMP and the University of British Columbia have called a noon hour news conference to offer what is described as an update on recent sexual assaults that have occurred on the university campus.

Sgt. Peter Thiessen says no further details about the update will be released before the news conference, to be held on UBC's Point Grey campus.

Three attacks on women occurred over three weeks, beginning in late September, alarming the university community and prompting additional security measures.

Women were also urged not to walk alone at night, leading to criticism that UBC and the RCMP should focus less on telling women to protect themselves, and more on condemning sexual assaults and finding the perpetrator.

The first attack occurred Sept. 28, when a woman was grabbed from behind and groped, and the confirmed attacks continued until Oct. 19, when a teenager was grabbed from behind, groped, and also reported being punched in the face.

In each case the attacker was identified as a tall, thin man in his late 20's wearing a black hoodie.
