A man has died in a road accident on the A35 in east Devon.
His vehicle left the road near Axminster on Friday afternoon and careered over a high hedge trapping him underneath.
Police are appealing for the driver of a dark coloured BMW who was at the scene, but left before leaving his details, to contact them.
PC Alan Mobbs said: "This man might be an important witness for us, so we are asking for them to come forward."
Police said the driver was believed to be in his 20s.
