A bit of a false alarm caused quite a traffic snarl along the south end of the Magnificent Mile Tuesday morning.
A lot of police after people spotted a metal bar with a spring wrapped in a black cloth taped to a flag pole in the 400 block of North Michigan.
Police closed off a section of the road as a robot inspected the object. The police bomb squad came in to take it apart.
At least one official called it a prank.
