Police have released photos of a man they want to speak to in connection with an indecent exposure incident on a Northern Line Tube train.
A man and the female victim both boarded the southbound train at Stockwell at around 8.4o pm on April 11. The man sat in the carriage next to the woman.
The woman soon noticed the man touching himself inappropriately while looking at her and another woman in the carriage. The man later got off the train at Colliers Wood.
Officers believe the man in the images may have information which could help their investigation.
