Officers from the Met's Roads and Transport Policing Command have released an image of a man they would like to speak to in connection with an allegation of a sexual assault at a bus stop near the Post Office on Burdett Road, in Tower Hamlets.
The incident occurred on 29 August 2016, at approximately 17:00hrs. The female victim was waiting for the bus, when the suspect approached her and inappropriately touched her.
The victim brushed him off and he went and sat on the bench at the stop, engaging in conversation with a female member of the public who had just arrived.
The suspect remained at the stop until a D7 bus arrived, which he then boarded.
He is described as being 5ft 7ins tall, with a short beard and wearing a khaki coloured top and loose trousers.
Anyone with information is asked to contact local police on 101 or tweet via @MetCC. Alternatively call Crimestoppers anonymously on 0800 555 111.
