A University of Maryland student was robbed at knifepoint Thursday in what university police say is the first on-campus robbery in more than a year.

About 11:45 p.m., the student was walking alone from a parking lot past Cecil Hall, a women’s-only residence hall, when he was approached by two men wearing masks, university police said.

One of the men had a knife and robbed the student.

The suspects then walked away from the scene, police said.

The student, who was not identified, was not injured. Police did not say what was taken from him.

Police issued descriptions of the suspects, who are still at large.

One suspect is described as a black man, 6 feet tall, medium build, unknown age, with dreadlocks, and wearing black ski pants, a black shirt and a face mask.

The other suspect is described as a black man, 6 feet tall, small to medium build, unknown age, and wearing dark clothing and a face mask.

The investigation is ongoing. Anyone with information about the incident or the suspects’ identities can call 301-405-3555 or e-mail investigation@umpd.umd.edu.
