A man has turned himself in to police after three Northwestern University students were robbed at gunpoint last Sunday.

Shortly after, police released a surveillance picture from a convenience store in Skokie.

Police say the men used a credit card stolen from one of the victims.

The man on the left -- who turned himself in -- is identified as 23-year-old Timothy Blue. He was later identified in a police line-up.

The second person in the picture, on the right, has not yet been caught.
