Oakbrook Terrace police are searching for a man who robbed a convenience store Sunday night -- minutes after attempting to commit another robbery.

Police Chief Mark Collins Wednesday said the attempted robbery was reported about 10:30 p.m. Sunday on the 500 block of east Roosevelt Road.

A cashier at a restaurant told police that a man was waving a gun outside the drive-through window. The man was demanding that the cashier open the window.

By the time police arrived minutes later, the man had left.
