Three would-be robbers tried to hold up a commercial bakery on Chicago’s Northwest Side on Nov. 25, but left empty-handed after some of the workers escaped and called authorities, police said, according to a report in the Chicago Tribune.

The three, all wearing masks, entered Chicago Sweet Connection Bakery at 5569 N. Northwest Hwy., through an employee entrance a little before 1 a.m., said Chicago Police Department News Affairs Officer Laura Kubiak. Two of the robbers appeared to be men, but the gender of the third robber was not specified in initial information.

One of the men pointed a gun at an employee, as another of the robbers guided other employees into a walk-in cooler, according to police. But some of the workers were able to flee the scene without being forced into the cooler and were able to call police.

The would-be robbers realized their plan wasn't working and fled through the employee entrance without taking anything of value from the commercial bakery, which distributes a variety of baked goods, especially desserts, in several Midwestern states.

When police arrived, they deployed police dogs, but a search of the building did not turn up anything.

No one was injured in the attempted robbery. Police did not have a more detailed description of the would-be robbers.

Chicago Sweet Connection is a wholesale bakery, delivering to five states: Michigan, Wisconsin, Indiana, Iowa, and Illinois, according to the company’s website. Built on more than 30 years of experience, the once small Chicago-based Sweet Connection Bakery has grown from just a few delicious dessert items to the most expansive line of delicacies that can be found.
