Police have released CCTV images of a man they want to speak to in relation to an indecent exposure on a train.

The incident took place on the 12.40pm train from Fenchurch Street to Shoeburyness on Saturday, January 10.

A female victim, who boarded the train at West Ham, noticed the carriage she was sitting him had become empty due to passengers leaving at Barking and Upminster stations.

As she stood up to get something from her pocket, she noticed a man sitting in the seats behind her, who was exposing himself.

The man left the train at Benfleet.

PC Lauren Newling said: “I am keen to speak to the man in the CCTV image as he may hold vital information which could help us in our investigations.”
