Police are investigating an incident on the A27 which resulted in two motorcyclists being forced off the road, and one left with serious injuries.

Around 11.10pm last Thursday night (July, 13), a 49-year-old man from Chichester was riding a Triumph Trophy, along with a 21-year-old man from Barnham on a Harley Davidson.

They were on a stretch of road near Fontwell, when they were approached by a silver vehicle and dark coloured vehicle.

Both men were overtaken by the silver vehicle, and then the man on the Triumph was knocked off his motorcycle by the darker coloured one.

He was taken to hospital and has serious injuries to his arms, ribs, lung and foot.

Police said his injuries are not life-threatening.

Detective Constable Jo French of West Sussex Investigations at Chichester said:

“These incidents are being investigated as serious assaults and the outcome for both riders could have been much worse given the circumstances.

“It is not clear why these men were attacked.”

The man on the Harley was followed and run off the road at the War Memorial roundabout at Eastergate at the A29 junction of Fontwell Avenue, Nyton Road and Barnham Road.

He was then threatened and assaulted by three men carrying weapons, believed to be hammers and a wrench, but police said he didn’t suffer any injuries as a result.

His attackers are described as being in their 30s wearing dark clothing, and may have left the area in a van.

Anyone with information about the incident is asked to contact police online quoting reference number 1638 of 13/07.
