Two students, both men, were walking to Wheeler when a man approached them. The man pulled a gun out of his waistband and told the victim to drop his laptop, according to police.

The victim complied and fled into Wheeler Hall. Police searched the area but couldn’t find the suspect.

The suspect is described as 20 to 25 years old, around 5-8 and around 140 pounds, wearing a gray hooded sweatshirt, dark pants and dark shoes.
