Police have released CCTV after a man was seen to expose himself in front of train passengers in three separate incidents.

On each occasion a man is said to have exposed and touched himself inappropriately.

One of the alleged incidents happened on a Bromley South to Otford Time service, which passengers from Kent may have witnessed.

Another incident allegedly happened on a service between Blackfriars and Horley Times station, and a third time on a train between East Croydon and Bedford.

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