A male Northwestern student was robbed early Tuesday in the eighth attack on a student since the beginning of Fall Quarter, university officials reported.

The student was walking near the intersection of Ridge Avenue and Emerson Street at about 4:10 a.m. when a man came up behind him and demanded his wallet and cell phone, according to a security alert issued by the university. After the student gave the man his wallet and phone, the offender left the area.

The student was not injured or threatened with a weapon, according to the alert. The student told police he did not turn around or see the man’s face.

Evanston Police Department is investigating the incident in connection with the recent string of crimes affecting students, said Cmdr. Michael Perry of EPD.

Since late September eight students — including Tuesday’s victim — have been assaulted or robbed. The most recent attack before Tuesday occurred early Saturday, when a Chapin Residential College resident told police he was threatened and held at knifepoint on Sherman Avenue.

Vice President for University Relations Alan Cubbage said although the university is “obviously concerned” about the robbery, there are no plans to launch any new security initiatives.

“We’ve increased security on campus and off campus,” Cubbage said. “The university has taken a number of actions. Nevertheless these incidents are occurring and it’s unfortunate.”

University Police has stepped up patrols in response to the string of attacks, and the university has hired security guards to patrol areas on campus with golf carts. Also, two vans with trained security guards as drivers were added to the Escort Service.

The Purple Route shuttles soon will begin running three hours earlier, starting at 6 p.m., said Tamara Kagel, Associated Student Government student services vice president.

Despite added security measures, Cubbage said, students must take responsibility for their safety.

“We’re concerned that students are out at four in the morning walking alone,” he said. “We hope students would be more cautious given the number of warnings.”

Kagel, a Communication senior, said ASG is trying to address safety concerns as well. A personal safety bill was presented Tuesday at ASG’s Rules Committee meeting.

The bill, which is on the agenda for tonight’s Senate meeting, calls for university administrators to purchase at least 1,000 personal keychain alarms for students at a cost of $6 each.

But Weinberg senior Paul Hong said being at NU still feels less safe than it did last year, especially off campus. Since the attacks began, he said, he always makes sure to leave friends’ apartments at 11 p.m., instead of 2 or 3 a.m.

“I hate feeling like this,” said Hong, who lives in Foster-Walker Complex, near where one attack occurred. “I’m restricted in what I can do.”

Hong is aware of added security measures but said he doesn’t see police when he goes off campus.

“I know there are supposed to be changes,” he said. “I just haven’t seen it.”
