Detectives investigating a sexual assault on board a DLR train have released this image in connection
At around 10.30pm on Friday 29 May, a woman was on the platform at Canary Wharf when a man approached and began to sexually harass her.
He then boarded the train and sat next to her, and as she tried to move away he grabbed onto her and sexually assaulted her, refusing to let her go.
The man only stopped when two other passengers came over to help, and he eventually got off the train at King George V station.
Detectives would like to speak to the man pictured, as they believed he may have information that could help their investigation.
Anyone who recognises him is asked to contact British Transport Police by texting 61016 or by calling 0800 40 50 40, quoting reference 153 of 2 June.
Information can also be given anonymously to Crimestoppers on 0800 555 111.
