TWO young school girls were left distressed after a pervert exposed himself in a Rishton alleyway.

The 12-year-olds were sitting in an alleyway off Danvers Street waiting for a local shop to open when the man approached them. He exposed himself and walked away.

The incident happened at around 9.30pm on Saturday night and left the girls shocked, police said.

The man has been described as white, between 40 and 45 years old and of slim build. At the time, he was wearing black glasses and had dark, very short hair.

Police launched a man hunt and have appealed for any witnesses to come forward.

Detective Sergeant Julie Cross said: “This was very unnerving for the two young girls and it has left them both distressed and so we would appeal to anyone who has any information at all to come forward and contact us as soon as possible.”
