Police pursued a Greyhound bus across the Wisconsin-Illinois border late Friday night after hearing reports that one passenger was behaving in a disorderly manner and possibly armed with a gun. A suspect was taken into custody around midnight, and about 40 other passengers were removed from the bus unharmed. An ABC affiliate reported Saturday morning that the chase occurred because the subject hijacked the bus and threatened to kill his fellow passengers. The report quotes law enforcement saying they used spike strips to forcibly stop the Greyhound.
