Police in Newham investigating the violent robbery of a vulnerable elderly man in August continue to appeal for information and witnesses to come forward.
The elderly victim, 82-year-old Ahmet Dobran, who uses a walking stick, was dragged to the ground by three men who pinned him down before forcibly removing his personal jewellery.
The attack took place on Sussex Road, E6, at about 18:55hrs on Sunday, 27 August.
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.
Detectives have released three new images of the men wanted for questioning in connection with the incident along with a new image of Mr Dobran who is currently in critical condition in hospital.
PC Sam Bush, the investigating officer, said: "How three grown men can be so vicious in attacking and robbing an 82-year-old man with a walking stick is beyond comprehension.
“Over the past month, Mr Dobran has been in and out of an induced coma, and he is now on a high dependency ward in hospital. He needs breathing apparatus, which includes a tracheotomy. Doctors are not sure if this is permanent or temporary.
“The men still have not been identified, and I believe that they are not local to the area of East Ham, or even Newham. Someone knows who the suspects are we need to catch them before they target anyone else, as they clearly have utter disregard for their victims and do not hesitate to use violence."
Statement from the son and daughters of Mr Dobran: "We are all devastated by it all. This attack has taken his independence away. Our father is not an indoor person, and now he will be stuck in doors for the rest of his life. We are appalled at how someone can do this to an old man.
“He is now unable to fly to Cyprus to see the rest of his family, he used to go there a couple of times a year.
“Can someone please come forward with information regarding who done this to our father, someone knows who they are. The people who did this could do this to someone else, with no guilty conscience."
