Officers are appealing for information after a man broke into a woman's flat in the Isle of Dogs and sexually assaulted her.
The Met Police have released at CCTV still of a suspect wanted for questioning after the incident on Manchester Road in east London.
The victim woke up at her home at around 6am on May 12 to find the man attacking her.
She managed to escape the room before the intruder fled out of the front door.
Police believe the same man was seen in another flat in the same block just moments before the attack, when a couple woke to find him standing in their bedroom.
He ran off before they could confront him.
The suspect is a white man in his 20s who was wearing black clothes and a wearing a black coat with a white collar and white trainers.
Detective Constable Daniel Cooke said: "This was a terrifying assault for a young woman who woke up to find someone in her own bedroom, a place she should have been safe.
"We are keen to hear from anyone who might recognise the man in this image, particularly from the clothing he can be seen wearing.
"Inquiries into both break-ins continue.”
Any information can be reported by calling 101 with reference 1575/12May or Crimestoppers anonymously on 0800 555 111."
