Surrey Police is appealing for witnesses after two men verbally abused a woman over a 20 minute period from their car on the M25.
The victim was driving anti-clockwise on the M25 on Monday 14 April at 5.40pm when the incident occurred.
It was at Junction 13 near to the Surrey border with Berkshire that she noticed a Ford Transit pick-up pull alongside her in slow moving traffic.
The occupants, two white males, began laughing and pointing at her. For the next 20 minutes they hooted their car horn and took pictures on their mobile phone causing her some distress.
The victim managed to move into the lane behind them so as not to be in direct contact.
She lost sight of them near to Junction 6 at Godstone and believes they may have driven into Kent.
The suspects are two white males, aged 20-30. They had a scruffy appearance with light hair. The passenger had tattoos on his arm and was taking the photos.
Anyone with information should contact Surrey Police on 101 (999 in an emergency) quoting the reference number 45140030408.
