EVANSTON, Ill. (CBS) — A Northwestern University student was robbed by wooden stake-wielding assailants Monday evening, as he walked through the parking lot of a graduate dormitory.

Just after 11 p.m. Monday, the student was the victim of a robbery while walking through the parking lot of Engelhardt Hall, a high-rise apartment dormitory at 1915 Maple Ave. a few blocks west of the main campus.

The victim said he was approached by two men in the parking lot. One grabbed him by the neck, while the other brandished the large wooden stake.

The robbers demanded money, and the victim gave them $10 and his iPhone, Northwestern University police said.

The assailants fled west on Foster Street, while the student used an emergency blue-light phone to call police. He was not injured, police said.

The suspects are still at large. They are both described as African-American males standing 5 feet 7 to 5 feet 8 inches tall, with thin builds. The suspect who grabbed the student was also described as wearing a black tank top and a black baseball cap worn backwards, police said.

University police advise everyone to be cautious when traveling at night, and report any suspicious activity to use the blue-light phones, or call 011 for university or Evanston police. Anyone with information on the robbery is asked to call Northwestern campus police at (847) 491-3456.
