British Transport Police (BTP) is appealing for information after a man exposed himself and performed an indecent act in front of a woman and her two children at Hornbeam railway station.
Officers would like to speak to anyone with information about the incident, which took place at around 2.15pm on Friday, 31 January 2014.
Police Constable Mark Birdsall from BTP is investigating. He said: The victim, a 22-year-old woman from Harrogate, was on the platform at the station with her two young children when she was approached by a man.
He then attempted to engage the woman in conversation before performing an indecent act upon himself in front of her and her children.
The man has been described as aged between 40-50, approximately 5ft10 with grey stubble and a spoke with a North East accent. He wore a grey coloured coat; a grey fine knit beanie hat and blue denim jeans.
Officers have launched an investigation into the incident and are reviewing CCTV from the surrounding area.
PC Birdsall continued: This was clearly an extremely distressing experience for the victim and her family and I would urge anyone with information to come forward and speak to us.
Unwanted sexual behaviour of any kind is not tolerated anywhere on the rail network and we take all reports seriously.
