Can you help officers from British Transport Police identify this man? 

They would like to speak with him in connection to a sexual exposure on board a train travelling between Grays and Tilbury. The incident happened between 6.48am and 7am on 12 March. 

A 14-year-old girl was sat on the train when a man sat across from her in the aisle and started to touch himself inappropriately. He stared at the girl whilst touching himself. 

He then left the train at Tilbury.

Officers would like to speak with the man in the CCTV image as they believe he has information that could help the investigation.
