POLICE believe they have narrowed down which type of lorry was involved in a hit and run incident on the A30 which left a 42 year-old man from Launceston with serious head and leg injuries.
Emergency services were called to the A30 at Temple near Bodmin just before 8pm on Tuesday night (February 12) where paramedics and members of the public had been treating the casualty.
Police say the man appeared to be walking from Bodmin towards Launceston when he was struck from behind by the lorry.
A police spokesman said: "The collision left a significant amount of debris at the scene.
Investigators from the Serious Collision Unit are keen to speak to anyone who may have witnessed the collision or the events leading up to it.''
Police have recovered the debris from the scene, which are two nearside mirrors from a heavy goods vehicle. They believe the lorry will either be a Volvo FL or FE, an LF DAY or a Renault 1818 or 2711.
Police are appealing to anyone who has any information about this type of vehicle or to dealers who may have be asked to repair such damage to call them on 101 quoting log number 0696 120213.
