Police are hunting a naked man who approached members of the public in North Yorkshire at the weekend.
A middle-aged man indecently exposed himself at Nidd Gorge, a beauty spot between Harrogate and Knaresborough, on Sunday afternoon.
The man was wearing only blue trainers, a white baseball-style cap and a grey rucksack at the time of the incident, police say.
He fled the scene, towards the Scotton end of the Nidd Gorge walk, after police were called.
Officers are now appealing for help establishing the identity of the man and are asking people to report any further sightings or similar circumstances to assist with the investigation.
The man is described as approximately 5ft 10ins tall, very thin, with a pale skin tone and aged in his 40s, with sandy coloured hair and a short beard.
