A man has been arrested following a dramatic police chase in Melbourne in which the driver jumped from a moving van and was hit by a police car. The pursuit began with the driver of a severely damaged van weaving through traffic and into the city's western suburbs. The van side-swiped at least one other vehicle with smoke and sparks seen emanating from the vehicle's burst tyres. A short time later the man jumped out of the driver-side window and was hit by a police car. He shows no signs of serious injuries and has been taken into custody.
