A photo has been released as part of an investigation into a woman being sexually assaulted on the London Underground.
The 19-year-old was on the Piccadilly line when a man who had been sitting next to her stood up and deliberately fell onto her.
He then sexually assaulted her, stood up and smiled at her., British Transport Police said.
This took place when the train reached Holborn station, at around 5.30pm on August 17 last year.
The British Transport Police released a picture of a man they believe may be able to help with the case.

The annual number of sexual offences recorded on the Tube have risen, British Transport Police (BTP) figures showed in January.
There were 909 sexual offences, excluding rape, recorded between December 1, 2022 and November 30, 2023, compared to 866 in the previous 12 months.The figures also show that violent crimes rose, with 3,542 incidents reported, up from 2,963 in the previous year.
The number of robberies on the Tube network in London saw a steep rise, with 738 cases reported, up from 442.
A spokesperson for Mayor Sadiq Khan told the Standard crime rates on the Transport for London (TfL) network are considerably lower than on National Rail services and that crime on the tube network largely reflects national crime trends.
The Mayor's spokesperson said: "We want everyone to feel safe and be safe when travelling around London at all times, and the safety of women and girls is an absolute priority for the Mayor and TfL."
