A man stripped naked after spotting a 20-year-old woman walking in a field in Teesside.
The woman was exercising her dog near Belmont Farm in Belmangate, Guisborough, on Tuesday evening when she saw a fully-clothed man.
But she fled after she noticed he had taken his clothes off and was walking towards her.
The man is described as white, with a chunky build and around 40 years old wearing black shorts and blue t-shirt.
