TFL and Met Police are working in conjunction on a campiagn to make public transport safer. This week their 'Report It to Stop It' campaign has been running to raise awareness of the special channels to report any unwanted sexual advances experienced on the tubes, buses, or trains in London. This could be anything of a sexual nature, from groping to sexual comments, or even someone taking photos of you without your consent. There is no pressure on the victim to prove the nature of the incident, they will investigate for you.
Watch the campaign video, and find out more information on the scheme here.
