Police have arrested and charged 26-year-old Nicholas Cooke with three offences of outraging public decency.
Cooke, of The Paddock, Aughton was arrested by officers on Friday, August 1.
His arrest comes after police appealed for information following three reports of a man touching himself inappropriately inside a silver car.
The first incident took place at around 7.45pm on Tuesday July 15 on Butchers Lane. A woman in her 30s reported that she saw a man touching himself inappropriately in a parked car.
A man was again seen touching himself inappropriately by a 16-year-old girl at around 8pm on Monday July 21 on Brookfield Lane.
The third incident took place at around 8pm on Tuesday July 29 again on Brookfield Lane. Two 15-year-old girls were cycling along the road when they saw a man sitting in the driver’s seat of a parked car. As the girls passed they saw that the male was touching himself inappropriately.
As the girls continued to cycle, the vehicle followed them and the man was seen touching himself inappropriately again as the girls cycled onto Mickering Lane.
The man was described as white, with a tanned complexion, aged in his 20s or 30s with short dark coloured hair.
He was believed to be driving a small silver hatchback vehicle.
Detective Inspector Warren Atkinson said: “We are aware that these incidents have caused a lot of worry in the local community and we worked hard to try and catch the person responsible. We will not tolerate this kind of crime in West Lancashire. ”
Mr Cooke was released on bail and is due to appear at Ormskirk Magistrates on August 19.
