Police are investigating after a man carried out a lewd act in public in Rainworth on 4th December.
A woman, aged 40, was walking with a young child along Pit Lane - a track that runs between Potters Snooker Club and the sports pavilion on Kirklington Road - between 2pm and 3pm.
She stopped briefly to put the child into the pushchair and noticed a man who was exposing himself.
The offender is white, in his late 30s to early 40s, about 5ft 4” tall, slightly overweight, with a bald head.
He was wearing a short-sleeved pink shirt which was unbuttoned and a pair of black framed sunglasses.
Anyone with information should call police on 101 or Crimestoppers anonymously.
