CHICAGO (CBS)-- Four armed robberies were reported in just 15 minutes and a mile and a half apart on the Northwest Side. 

The first robbery occurred just before 9:30 p.m. on Division Street and Maplewood Avenue. A man exited a car and robbed a 60-year-old man at gunpoint.

About five minutes later, two men tried to rob two people in a front yard near Rockwell and Lemoyne streets, but the victims ran to the back of a home.

Then, at Fairfield and Bloomingdale avenues, two men took a purse from a woman getting out of her car.

Ten minutes later, two men robbed a man of his wallet and phone while he was unloading groceries in the alley near Sawyer and Wabansia avenues.

Police have not said whether the robberies are connected.
