A tour bus mainly carrying Polish tourists was going too fast during a downpour when it crashed and flipped over on an upstate New York highway, leaving 30 people with minor injuries, police said. State police Capt. Eric Janis said Thursday that 19 people were treated at three Binghamton-area hospitals after the Wednesday night accident. He said police were trying to confirm that all the injured had been released. They included a woman who was trapped underneath the bus and was dug out by emergency crews.
