CHICAGO -- A United Airlines flight bound for Chicago was grounded this morning after a fake explosive device was found in a traveler's suitcase.
Customs agents discovered the mock device in a pre-clearance area at Toronto’s international airport.
58-years-old Joseph Galaska, from Milwaukee, was arrested and is now charged with Mischief.
Passengers were forced to wait on the tarmac for several hours, before being escorted off and re-screened.
