The mugger asked what time it was, and when he saw the student's smart phone, he punched him in the face and stole it.
Northwestern University students are on alert after a student was attacked and robbed Saturday night.
It started around 11:30 p.m. at Sheridan Road and University Place on the Evanston campus. The attacker came up behind a male student and at first, just asked him what time it was. The student pulled out his smart phone to check the clock, and told him the time.
As the student walked away, the man again came up behind him, this time grabbing the student and demanding his phone. The thief claimed to have a knife, punched the student in the face, and grabbed his smart phone. The man then pushed the student to the ground and ran away.
The student chased his attacker, but was not able to catch him.
Police described the attacker as a black man, 18 to 22 years old, about 6 feet 1 inch tall and weighing about 180 pounds with an average build. He wore a multi-colored hat with stripes, and blue jeans.
Police ask anyone who thinks they saw the suspect or the attack to give them a call.
