Following an incident in which a man was assaulted in a layby on the A422, Bedfordshire Police is appealing for a van driver to come forward.
The incident took place between 5.30pm and 6.15pm on Tuesday 2 March off the A422 near Stagsden.
A man in his 30s has been arrested in connection with the incident and released on bail.
PC Shauna Brown, investigating the case, said: “We believe a van was parked in the layby at the time of the incident so are really keen to speak to the driver.
“The incident happened on a public road at a time when people may have been returning home from work.
“If you were in the area at the time or have any information, please get in touch with us. We would also ask people to check their dashcam footage in case there is anything that may help our enquiries.”
