A man has died following a robbery in Newham last summer.
Ahmet Dobran, 82, who lived in East Ham for the majority of his life, was attacked and robbed by three men on Sussex Road at about 18:55hrs on Sunday, 27 August 2017.
He died in hospital in the early hours of Monday, 15 January.
The victim's family has been informed. A post-mortem examination is yet to take place.
As a result of the attack Mr Dobran sustained three fractures to his vertebrae after one of the three men grabbed him by the neck whilst the others reigned blows to his back and arms.
They then forced him to the ground, where they removed his gold bracelet and Longine wristwatch.
The attack aggravated other conditions, such as Parkinson's, and a cancer the victim was receiving treatment for.
Police have previously released CCTV images of three men they want to trace in connection with this attack. One man - aged 33 - was arrested and charged on 12 December 2017 with robbery but two men are yet to be identified.
The Homicide and Major Crime Command have been informed but at this time the investigation remains with officers in Newham.
Detective Inspector Iain Wallace, of Newham CID said: "Mr Dobran was hospitalised following the attack in August and had been in an induced coma for several weeks until he was recently introduced to a nursing home. Sadly Mr Dobran's health deteriorated soon after and he was taken to hospital and passed away.
"His family are utterly devastated and, whilst we are unable to ascertain at this time that he died as a result of the attack, we do know that at the very least it may have aggravated other existing conditions. We await the results of the post-mortem to determine this.
"Whilst one of the men has now been identified and charged we are still keen to trace two other men who are still outstanding. Someone knows who these men are and I would urge them to come forward to stop thm from using the same level of violence on another vulnerable person."
Anyone who recognises the men pictured is urged to call police on 101 or Crimestoppers anonymously via 0800 555 111. You can also tweet information to police @MetCC.
