Two teenagers, one wielding a knife, the other serving as a lookout, staged an armed robbery in Evanston Tuesday night at a Mobil gas station at 1950 Green Bay Road, fleeing with an undetermined amount of cash.
The gas station attendant activated a panic alarm at about 9:30 p.m. Witnesses told police of two male blacks running north on Green Bay and that one of them threw away a metal object, which police recovered and found it to be an eight-inch bladed knife, according to Cmdr. Joseph Dugan of the Evanston Police Dept.
The teenager with the knife was identified as wearing a light blue winter jacket. No description was available for his companion who was serving as the lookout.
Evanston detectives are using surveillance video in an attempt to identify the offenders, Dugan said.
