Officers investigating a series of indecent exposure offences on the London Underground have released CCTV images of a man they believe may have information which could help their investigation.
On Friday 10 September between 1pm and 8pm a man on-board a Piccadilly Line Tube train exposed himself inappropriately to victims on four separate occasions.
On each occasion he rustled a carrier bag and made noises so the victims would look at him.
Officers believe the man in the images may have information which could help their investigation.
Police ask anyone who recognises him, or has any information, to contact British Transport Police by texting 61016 or calling 0800 40 50 40 quoting reference 2100068053.
Alternatively, you can contact Crimestoppers anonymously on 0800 555 111.
