Witnesses to a potential assault at Clacket Lane Service Station on are being asked to come forward.

Detectives investigating the "altercation" are urging anyone who saw a white Volkswagen van in the area to get in touch.

Officers believe the incident happened at around 4pm on Saturday at the south-bound service station of the M25 and involved a number of men in and around a white van.

The van has a sliding door on the right hand side, with window panels on either side, and was parked in the car park near a bush at the time.

Detective Constable Craig Giles said: “This would have been a busy time at the service station and so we are sure that there would have been more witnesses to this incident, or who saw the van and or its occupants – either on the M25 towards Kent or at the service station.

“Speaking to anyone who saw anything suspicious, as well as those in the van are our priority as we are keen to find out the exact circumstances of what happened.

“I would urge anyone with any information about what happened to come forward and help us with our enquiries, or report any information in anonymity to the independent charity by calling 0800 555 111.”

Anyone with any information is asked to call Surrey Police on 101, or report it online here, quoting reference number 45170009575.
