The hunt for a man who was seen touching himself near a Fleetwood school continues, police said.
A 21-year-old man who was arrested in connection with the incident, near Rossall School, has been released without charge.
I urge anyone with information to contact police directly on 101
The man, from Thornton, was arrested after an Evofit image of the suspect was issued last month.
It follows reports a man indecently exposed himself on the coastal path behind the school at around 7.30pm on August 18.
A woman who was walking nearby reported allegedly seeing him touching himself as she passed.
Lancashire Police said it is still investigating the incident and issued a fresh appeal for information.
A force spokesman said: “A 21-year-old man from Thornton was arrested on suspicion of indecent exposure but has since been released no charge.
“I urge anyone with information to contact police directly on 101.”
