Police want to speak to this man following a sexual assault on a teenage girl.
The incident took place shortly after 10.20pm on July 26, when a 17-year-old girl got off a train in Bletchley with a man and walked with him to Tinkers Bridge.
As they walked along the Redway, the man kissed the girl on the next and touched her inappropriately. She pushed him away and flagged down a member of the public in H9 Groveway.
Officers would like to speak to the man in the CCTV image below, who they think may be able to help with their enquiries.
The man pictures is white, around 5ft 6in tall, with short light-brown hair. He was wearing a polo shirt, jeans and white Lacoste-type shoes.
Anyone with information is asked to contact PC Sarah Lucas on 101.
