A series of sexual assaults at UBC has put the campus on high alert and students have been warned not to walk alone during late hours.

The latest incident saw a 17-year-old student assaulted while walking back to her residence just after midnight on Saturday.

The attacker put his hands around the woman's hips, tried to drag her into a wooded area and punched her in the face. He ripped at her clothes but later ran off when she screamed for help.

The suspect is described as a tall, thin man in his 20s or 30s with a possible American accent.

The news stirred a quick response from UBC as staff set up meetings on Saturday with students living in residence, VP students Louise Cowin told The Globe and Mail.

"There was very direct messaging from residence advisers to bring to [students’] attention that this was the third assault that had happened," she said.

"Before, the messaging had been very advisory in nature, where this was very explicit – ‘do not walk alone, and get out your cellphone and put these numbers in it.’”

Those numbers include that of AMS Safewalk, a service that provides a co-ed escort that will take students anywhere they need to go on campus. The number is (604) 822-5355.

UBC students Elana Cooper and Rachel Stiyer attended one of the meetings at Totem Park Residence on Saturday, The Vancouver Sun reported.

Stiyer told the newspaper that students were told to walk with a friend, call Safewalk or contact Campus Security instead of traversing the campus alone at night.

She said she always felt safe on campus before but called the incidents a "wake-up call."

"It’s sad you have to take actions outside of what you would normally do in order to be safe," Stiyer said.

Barry Eccleton, director of UBC Campus Security, has stepped up patrols and put up signs reminding students to be vigilant and walk in pairs at night.

Security issues persist at other student residences such as Ponderosa Commons, where a lack of door locks and security cameras has master's student Erica Sandhu concerned, CTV News reported.

"Anyone can just enter the building ... you don’t need a special key or a card to get in," she told the network.

"Anyone can come into the elevator at any time of the day and come up to the floors where the residents are."

Cowin told CTV News that Ponderosa Commons may not be secured due to construction delays, adding that she would look into the issue herself.

The latest incident follows another on Oct. 13 in which a 20-year-old woman was assaulted as she returned to her apartment at about 3:30 a.m. Another incident saw a 19-year-old woman flee a man who tried to grab her on Sept. 28.

Police suspect a single person in all three sex assaults, Global News reported.

The investigation was disclosed Tuesday after a preliminary examination conducted earlier this year concluded there was enough evidence to move ahead with a full probe, Assistant Attorney General Thomas Perez said. Lawyers from the Justice Department's civil rights division will look at all 80 sexual assaults reported by women in Missoula over the past three years. Eleven sexual assaults involving university students have been reported in the past 18 months. Prosecutors were trying to figure out whether those university complaints were included in the total number of citywide assaults reported.

  • Oklahoma State Sexual Assault Reporting - Reviewed By University Task Force

On Thursday, OSU President Burns Hargis announced he asked the Board of Regents' task force to review the school's handling of the sexual assault complaints. The task force was formed in July to review school policies and ensure a situation like the Sandusky scandal at Penn State does not unfold at OSU. Hargis said in a statement that OSU "cannot leave any doubt that we are indeed properly and appropriately handling sexual misconduct allegations," Tulsa World reports.</blockquote>

  • Southern Methodist University -- Launches Task Force After String Of Sexual Assaults Reported

    <a href="http://www.huffingtonpost.com/2012/10/12/southern-methodist-sexual-assaults_n_1959302.html">Oct. 12, 2012 report</a> from HuffPost: <blockquote>Two students in separate cases were arrested last month on sexual assault charges. However, it raised eyebrows as people noted it took eight months to bring charges in one case while only a few days in the other. In response to the controversy, SMU announced a special task force to review how the school handles reports of sexual violence. Administrative action aside, problems persist on the Texas campus. On Wednesday, just a day before the first task force meeting, students received a crime alert warning of another sexual assault; this one allegedly targeting a young woman in her apartment west of campus by an acquaintance and fellow SMU student. The incident became the fifth sexual assault reported this year and the third in the past six weeks to go under investigation by University Park police. At least 40 sexual assaults were reported since 2006, according to the SMU Daily Campus, and almost all of them from SMU students. Over the past 25 years, more than 100 women at SMU reported being sexually assaulted.</blockquote>
