Police say two Northwestern University students were the victims of a home invasion early this morning at their downtown Evanston apartment.
The students told police a man broke a window in the rear door of their second floor apartment in the 600 block of Clark Street to get in.
He then threatened them, claiming to have a weapon but not displaying one, and stole two laptop computers, two wallets and a book bag from the apartment.
The students, who were not injured, called 911 and Evanston and NU police unsuccessfully searched for the robber, who was described as a male wearing dark clothing and a stocking cap.
Residents are asked to call the Northwestern University Police Department at 847-491-3456 or the Evanston Police Department at 847-866-5000 if they have information that may assist in the investigation.
Update 4:15 p.m.: Evanston Police spokesman Perry Polinski says officers took a person of interest in the case into custody not long after the incident, but the victims were unable to positively identify the suspect and he was later released.
Polinski says police are continuing their investigation and will be checking to see if surveillance cameras in the area may have captured images of the robber.
