Police investigating a knife point attempted robbery and sexual assault in Newham continue to appeal for information and witnesses.
A £10,000 reward is now available for information leading to the arrest and conviction of the individual responsible.
At approximately 22:30hrs on Wednesday, 3 May 2017, the female victim was returning from work when she heard someone running up behind her on Fentons Avenue, E13.
She turned to see a man with a knife, thrusting it towards her before demanding money from her; threatening to kill her if she did not oblige. The victim explained that she had no cash, but the suspect insisted she show him the contents of her purse.
When she was able to prove her claim, the suspect threw her bag to the floor, before sexually assaulting her and running from the scene.
Detectives from the Child Abuse and Sexual Offences Command (CASO) have issued CCTV footage and an e-fit of a man they would like to identity in relation to their investigation. The footage shows the man in the vicinity of the incident shortly before it took place.
He is described as black, between 18 and 23 years old, approximately 5ft 5ins tall, with short black hair and spots or scars on his cheeks. He wore a rolled up balaclava as a hat, dark trousers and trainers and a distinctive dark jacket/top which was lighter on the torso area, had a dark strip going to midway down the front, and dark sleeves with a light patch on the left arm.
Detective Constable Tom Prosser, from CASO, said: "This was a terrifying ordeal for the victim which left her shaken and scared to go out. The suspect is clearly a dangerous individual who we need to identify; and it is hoped that the offer of a significant reward will assist.
"I would urge anyone with information which could assist the investigation to call 020 8217 7415. To remain anonymous call Crimestoppers on 0800 555 111."
