Cumbria Police say they've had reports of "regular sightings" of a man who fits the description of someone who exposed himself in the Windermere area at the weekend.
It happened at around 1.30pm at Orrest Head on Sunday, when the man exposed himself in front of a woman.
He's described as white, of medium build, with short and greying hair.
He was wearing shorts, a T-shirt and had a green rucksack with him at the time of the incident.
Anyone with information which could help to identify the man should contact Cumbria Police on 101, quoting log number 177 of June 19, and ask to speak to PC Stuart Game from Kendal Police.
