Police have appealed for witnesses after a group of around 30 people attacked workers from an HS2 construction site in Small Dean, Wendover, on Friday (26 March).
Thames Valley Police said it was investigating a violent disorder and assault after nine members of security staff were injured and property was damaged. The site sits on an 80km section of HS2 phase one, being constructed by EKFB, a joint venture between Eiffage, Kier, Ferrovial and BAM Nuttall.
Police said the incident occurred on the A413, with passing traffic narrowly missing people on the road.
A spokesman for Thames Valley Police said: “This was an unacceptable outbreak of violent disorder where a number of people were attacked in what appears to have been a pre-meditated and orchestrated incident.
“This incident took place in close proximity to the A413, and although thankfully no one was seriously hurt, this was a serious incident.
“We are appealing to anybody who was driving in the area at around the time and who has dash-cam in their vehicles to please check this and contact the police if it has captured anything that could assist this investigation.”
