Police are appealing for information and witnesses following an assault in Hemel Hempstead.
Between 10.15am and 11am on Sunday, May 27, a man aged in his 40s was involved in a verbal altercation at the traffic lights on London Road, near McDonalds.
He was then followed by a man in a small black hatchback car to London Road between the junctions with Two Waters Road and Station Road where motorists got out of their vehicles.
The hatchback driver then violently assaulted the other man, who suffered a broken collar bone, a laceration to the back of his head and a broken toe.
PC Natalie Williams, who is investigating, said: “This was a violent attack, which left the victim requiring hospital treatment and surgery to repair his broken collar bone.
“The offender is described as a black man, around 5ft 10in tall, of slim to medium build and aged in his 30s.
“I’m appealing for anyone who saw the incident or has information that could help us identify the offender to get in touch.
“I’d also like to hear from any motorists who were in the area at the time and may have captured dash cam footage of the altercation at the traffic lights or the assault.”
Anyone with information is asked to contact PC Williams by emailing email@example.com, calling the non-emergency number 101, quoting crime reference 41/1513/18 or report information online at https://www.herts.police.uk/Report.
