Collision investigators have renewed their appeal for witnesses following a fatal road traffic collision in Somerset last month.
The incident happened on 19th May on the A359 near to the Wanstrow to Nunney Catch roundabout.
A tractor was in collision with a motorcycle. The pillion passenger died and the rider was seriously injured and remains in hospital in a critical but stable condition.
Avon and Somerset Police are particularly keen to speak to the driver of a white van and the driver of a Kia motor vehicle, who were both travelling towards Nunney Catch around the time of the collision and stopped at the scene.
Police believe both drivers may have witnessed the incident and could have crucial information to help with their enquiries.
Anyone able to help is asked to contact the collision investigation unit on the force number 101.
