YPSILANTI, Mich. (AP) -- Three Ypsilanti Township teenagers have been arrested in a robbery and assault on a Michigan college student.
The Ann Arbor News reports that the teens -- ages 17, 16 and 15 -- are being held in the Washtenaw County Jail and are expected to be arraigned Saturday.
Another 16-year-old still is being sought.
Police say a 19-year-old Eastern Michigan University student was followed Tuesday night as he walked to his car from an Ypsilanti restaurant. He was ordered at gunpoint from the vehicle and struck in the face with the weapon.
The four suspects were unable to drive away in the student's car because the street was too icy.
The student tried running away through backyards in the area, but was caught and had his wallet taken.
