A report of an armed robbery near Kansas University’s Student Recreation Center on Tuesday night prompted the university to send out an alert to its students and staff warning them to stay away from the area.

The robbery was reported about 7:45 p.m. and KU sent its alert a few minutes after 8 p.m. The Student Recreation Fitness Center is on the south side of the KU campus, along 18th Street between Arkansas and Alabama streets. The robbery reportedly occurred in an alley in the 1800 block of Arkansas Street.

According to KU, Lawrence police are leading the investigation. KU officials described two suspects in the case as being white men. The first suspect was described as 5-foot-9, 150 to 190 pounds and wearing black puffy jacket. He had a revolver.

The second suspect was wearing a dark shirt-jacket, possibly a hoodie, and wore a baseball cap under his hood.

According to Lawrence Police Sgt. Damon Thomas, the suspects demanded the victim’s belongings, including a cell phone and iPod that were later found at the scene. One of the suspects reportedly punched the victim, a 31-year-old male KU graduate student, during the incident.

Anyone with information is asked to contact Lawrence police.
