MOTHERWELL, Scotland -- Police say a roller coaster derailed and crashed at a theme park in Scotland, injuring eight children and two adults.

The accident took place Sunday afternoon at the M & D's theme park at Strathclyde Country Park in Motherwell.

Police Scotland Chief Inspector David Bruce told reporters at the theme park that five gondolas on the Tsunami roller coaster ride detached from the rails as they rounded a bend, struck the superstructure and fell about 20 feet to the ground.

Bruce says the injured are being treated at hospitals in Glasgow. He did not have details on their condition.
