Police have released CCTV images of a man suspected of sexually assaulting a young woman on the upper deck of a bus in Lewisham.

The victim, in her early 20s, reported being assaulted on the 453 in the New Cross area on Thursday, May 2, by a man who boarded the bus at around 3.45pm.

Once she realised what he was doing, she confronted the man, who then moved to the lower deck before getting off the bus.

Officers want the public's help to identify and trace the man pictured.

He is described as black, around 40 years old, 6ft tall, of slim build, with a bald head.

Anyone with information should contact DC Teresa Moore from the Met's Roads and Transport Policing Command by calling 101 and quoting Cad 7111/02May19.

The Met is committed to working with Transport for London, to encourage people to report any unwanted sexual behaviour, as part of the Report It to Stop It campaign.

They encourage anyone who experiences or witnesses a crime to report it immediately by texting 61016, so that suspects can be caught.
