We’re appealing for help to trace witnesses and any dashcam footage after an assault in Stiby Road, Yeovil.
It happened between 9pm and 9.30pm on Wednesday 17 May, just after a collision involving a motorcycle and a black car in which there were no reported injuries.
A man needed hospital treatment for facial injuries after the incident.
A man in his 20s was arrested the next day on suspicion of wounding with intent and later released under investigation.
Officers are especially keen to trace the man pictured, a witness who stopped to help following the collision. He is described as a white man of large build with short dark hair. He is wearing dark-coloured jeans, a dark-coloured short-sleeved top and brown shoes.
If you have any information or dashcam footage please contact us.
