Authorities shut down the parking garage across the street from the Cook County Criminal Courts Building for about a half hour today after a law enforcement officer found two suspicious canisters attached to his vehicle.
The officer was leaving the garage at about 1:15 p.m. when he heard a rattling sound coming from his vehicle, according to Cook County Sheriff's spokesman Steve Patterson.
"The officer got out of his vehicle and found two rattling canisters adhered to his car," Patterson said.
The officer called for assistance. The investigation is being handled by members of the Chicago Police Bomb and Arson unit, Patterson said.
