In yet another brazen campus robbery, a University of Minnesota student studying Sunday afternoon in the Carlson School of Management was forced to hand over his laptop to a man who claimed to have a gun.

The student chased the robber as he fled and was able to retrieve the computer.

The 3:30 p.m. incident pushes the total number of robberies to 27 this fall with all but four occurring off campus. Most victims were targeted for their cellphones, laptops and tablets. Unnerved students have gotten a steady stream of alerts reporting robberies, muggings and sexual assaults on and near campus, prompting petitions, legislative hearings and increased police patrols.

The robbery on Sunday occurred in the Carlson School atrium on the campus' West Bank. Although the man robbing the student claimed to have a gun, he didn't show it, university police said. The student gave the robber his laptop, called for help and then chased the man through the building doors that face 19th Avenue and Fourth Street.

The robber dropped the computer, and the student, who was not injured, picked it up.

The suspect is described as a black man who is 5-feet-6 to 5-feet-8 tall with a medium build, unshaven facial hair and silver caps on his lower front teeth. He was wearing a navy blue hoodie, dark colored jeans and shoes that were white on the top half and red on the lower half.

Police said the suspect appears to have had an accomplice who stood as a lookout. He is described as a black man, wearing dark clothing with a boot-style walking cast on his left foot.

Last month, an armed man confronted a female student in nearby Anderson Hall, demanding the woman turn over her laptop. She handed him an empty bag and he ran. No arrests have been made in that case.
