At approximately 6.15pm on Tuesday 5 July 2016, a 19-year-old woman was walking her dog in Southbrook fields, near Cricklade Road, when she noticed a man wearing a beige baseball cap in an area of long grass and bushes.
She carried on walking and a few minutes later, the man walked out of the bushes and on to the path wearing nothing but the baseball cap. He stood on the path with his hands on his hips.
The woman turned around and ran away. She spoke to two women with a small child near the scene to make them aware.
The man is described as white, quite tanned, aged in his 70s, approximately 5ft 8 inches tall and of medium build. He had white, thin hair.
PC Cassey Evans said: “A man was seen riding a bike from the area around the time of the incident and we are keen to speak to anyone who may have seen him – I believe there may have been a number of people in the area at the time. If you have any information, please contact police on 101, or Crimestoppers on 0800 555 111 where information can be left anonymously if preferred.”
