Detectives are releasing two e-fits and appealing for information following an aggravated burglary in Redbridge.
The offence happened on Sunday, 30 April 2017 at 21:00hrs at an address in Stradbroke Grove, Ilford.
The female victim, who was in her early 50s, was home alone when she heard the doorbell ring.
She looked out the window and saw a female, with shoulder length brown hair and olive skin wearing a long cardigan over a shirt.
The female was in her 30s and was described as well presented and was smiling and waving at the victim.
The victim opened her door and on doing so two men forced their way inside the address causing her to fall backwards.
Suspect 1 put his foot on the victim’s side forcing her to stay down. He then produced a knife and threatened to kill her. He asked her where the money was and she noted he had an east European accent.
During this time suspect 2 went up to the first floor and searched both bedrooms, during which a quantity of cash and jewellery was taken.
While carrying out the crime the men spoke to each other in a foreign language.
Suspect 1 is described as a white male, aged about 40 to 42 years, of thin build and tall. He was wearing blue jeans, a black small leather jacket and yellow dirty boots.
The victim described his appearance as ‘strange’ because the jacket looked too small and he looked dirty. He had dark coloured hair cut in a short back and sides; it was spiky on top with dyed blonde tips.
Suspect 2 was short and fat, aged 45 plus, wearing a grey Nike tracksuit and he had a missing front tooth.
He was also dirty looking and had an east European accent.
The suspects remained at the address for about 30 minutes before making off.
DC Richard Draper, the investigating officer from the East Area Command Unit CID, said: "This was a planned and violent attack that left the victim bruised and very distressed. The two e-fits are thought to be very accurate and if you know or recognise these men call police immediately."
