Police have launched an appeal following an indecent exposure offence on-board a train in south east London.

Officers have released CCTV images of a man they would like to speak to in connection to the incident.

At just after 8am on April 3, the victim was travelling on a service between Bexley and London Victoria stations, when the man approached and sat near her.

In the appeal, the British Transport Police ( BTP) said that the man called the victim and as she turned around he was 'exposed and touching himself inappropriately' at around 8.45 am.

The victim then ran into another carriage and alerted other passengers.

It was reported that the man then moved carriages and when the train arrived at London Victoria, he ran from the train to the underground station.

Officers believe the man in the images may have information which could help their investigation.

If you recognise him, or have any information, contact BTP by texting 61016 or calling 0800 40 50 40 quoting reference 83 of 03/04/21.
