A man is sought after in connection with a series of exposure incidents on board Thameslink trains, including a service in East Croydon.

The man was seen to expose and touch himself inappropriately in front of passengers. He was seen doing this in three incidents which took place over the summer. The first was onboard a service between Blackfriars and Horley Times station, the second on a train between East Croydon and Bedford and the third on a Bromley South to Otford Time service.

British Transport Police (BTP) now believe that these incidents are linked.

Officers suspect that the man shown in the CCTV image may have information which could help them investigate.
