Police have released an e-fit of a suspected rapist who jumped over a fence and attacked a woman in a back garden.
The woman in her 30s was in a garden in Ellerton Gardens, Dagenham, in the early hours of 1 August when the ordeal took place.
The suspect is described as a very dark-skinned black man in his early to mid 20s and between 5ft 6in and 5ft 8in.
