Anyone with video footage of a firework display that took place near a fatal M5 crash has been urged to send it to detectives.
Avon and Somerset Police has called on people to hand over any such material, to help them piece together what happened on November 4, the night seven people were killed in a motorway crash near Taunton.
Officers are investigating whether smoke from the firework display at Taunton Rugby Club may have been a factor in the crash, which occurred in foggy and wet conditions at around 8pm.
Detective Inspector Sarah Davenport said: "You may think any information or footage that you have may not be relevant but please let us decide."
The crash claimed the lives of lorry drivers Terry Brice, from Patchway, south Gloucestershire, and Kye Thomas, from Gunnislake, Cornwall.
Father and daughter Michael and Maggie Barton, from Windsor, Berkshire, were also killed, as were grandparents Anthony and Pamela Adams, from Newport, South Wales, and battle re-enactor Malcolm Beacham, from Woolavington, near Bridgwater. One person remains in a stable condition in hospital.
The force has set up a dedicated email address - email@example.com - for people to send in their footage to the team of 30 officers investigating the crash.
