Police are re-appealing for information after reports of a man exposing himself in Alveston and Thornbury.
An e-fit has now been released of a man police are hoping to talk to in connection with their enquiries.
The man was seen jogging near Down Road Park at about 5:15pm on Monday 5th July 2010. He asked two girls aged 12 and 13 if they would help him find something he had lost in the bushes.
The girls moved away, but the man then exposed himself, before running off when an adult entered the park with another child.
Police have carried out door-to-door enquiries in the area and are now investigating two other similar incidents on the same day in the Knapp Road/Grovesend Road area of Thornbury.
One man was arrested but has been released without charge.
The man is described as white, aged in his 30s or 40s, about 5ft 10ins tall, clean shaven, with greyish receding hair.
Neighbourhood Sergeant Louise Boyce said: “Specialist officers have carried out video interviews with two of the girls and are arranging to speak to the others.
“I would ask parents to remind children not to talk to strangers. We are carrying out extra patrols in the affected areas.”
Anyone with any information which could help police enquiries is asked to contact DC Tracey Sparrow at Thornbury Police Station on 0845 456 7000. Alternatively contact the independent Crimestoppers charity on 0800 555 111.
