Two pedestrians were killed when a driver crashed into them in Cambridgeshire before fleeing the scene on foot.
The men were on a rural road near Yaxley when a BMW car collided with them just after 11am on Tuesday.
Police said the driver, a man in his 40s, then fled on foot and has not been caught. A police helicopter has joined the hunt.
An air ambulance was called for the two victims, who have not been identified, but they were pronounced dead at the scene.
