Police Officers are asking for help to identify a man who allegedly exposed himself to a 15-year-old girl in Ashgate.
The man, who is described as being white, well built and with dark hair, was wearing a jumper, blue jeans and was carrying a bottle shaped bag.
He is reported to have been walking down the middle of Ashgate Road, between Greenbank Drive and Cuttholme Road, between 6.30pm and 7pm on Wednesday, June 5 when the incident happened.
The man is then thought to have made his way towards Loundsley Green, and was last seen on a path near to Burbage Court.
