A man in his late 20s allegedly exposed his genitals to two women on an old railway path between Horncastle and Woodhall Spa.
Police are appealing for help to identify a man seen on the path, who had his running tights down around his ankles and was exposing his genitals before running off at around 11.30am on Saturday, August 25.
Two women who were walking from the Leisure Centre in Horncastle were passed by a man jogging in the same direction towards Woodhall Spa.
He briefly spoke to the women and around five minutes later, as the women continued their walk along they track, they saw him again.
That is when he exposed himself and ran away.
The man is described as white, in his late 20s, around 5’9 to 5’11 in height and of slender build.
He had short black hair which is described as wiry and a little curly, is clean shaven and appeared well spoken.
He was wearing black running tights, a bright blue long sleeved running top and unusually he was running in flip flops.
Neighbourhood Inspector Sarah Constantine said: “We believe this is an isolated incident and very unusual in its nature. We want to trace this man and I believe someone will recognise the description, especially as he was running in flip flops.
“The track between Horncastle and Woodhall Spa is regularly used by dog walkers and I wouldn’t want people to worry about walking along the track due to this one incident.
“Someone will recognise the description of this man, in fact, I’m hoping the person in question will contact us. Of course if anyone has any concerns or information then I’d ask them to contact us.”
