Detectives have released an image of a man they would like to speak to after an upskirting incident at Tottenham Court Road station.
A passenger noticed a man at the central London station tilting his phone upwards as he appeared to record two young girls at around 2:15pm on July 14.
The passenger challenged the man and followed him until he left the station.
British Transport Police believe the man in the image might have more information that could assist with their enquiries.
Anyone who recognises him is asked to text BTP on 61016, or call 0800 40 50 40, using the reference 321 of 14 July.
