The United States Postal Service bulk mail processing facility at 7500 Roosevelt Rd. was evacuated after an employee reported spotting a possible live hand grenade.
On July 12, at 8:33 a.m., one of the employees was unstacking the bins and reported seeing what looked like a hand grenade in a clear plastic bin. In keeping with the procedure, all employees evacuated the building and the Cook County bomb squad was called in. But when the postal inspectors arrived at the scene, it was determined that the hand grenade wasn’t live.
The bomb squad call was canceled and the postal employees returned to the center.
