The student told police a man pushed open the door of his apartment in the 2200-block of Sherman Avenue, walked into his bedroom and hit him in the mouth around 3:15 p.m. Monday.
The man then took off. It's not clear if he took anything with him.
In a security alert, university officials said the man entered through an unlocked back door. He did not display a weapon during the incident.
The student declined medical attention and did not give police a complete description of the suspect.
Evanston police are investigating the attempted burglary. They reminded residents to make sure their doors are always locked, whether they are home or not.
