The son of an 82-year-old woman who died after being mugged in her street said he has been "cut to pieces".
Ursula Craddock died nearly three weeks after being attacked
Ursula Caddock, also known as Joan, was knocked to the ground by a man as she walked along Halstead Road, Wanstead, east London on the morning of 8 April.
Police began a murder hunt after she died in hospital on Tuesday.
Her son David from Suffolk said: "It's my mum this time but next time it could be somebody else's". The attacker is described as black and 5ft 9ins tall.
Mr Caddock, who is in his fifties, said his mother had been mugged just yards from the house where she lived with her son Derek.
"He mugged her for the bag and then came back for a bus pass."
Paying tribute to the great grandmother, he said: "She walked with a walking stick but she certainly wasn't frail.
"She was in reasonably good health for somebody that age. She wouldn't give up. She was a very nice person."
After the attack in April, the pensioner was taken to London's Whipps Cross Hospital suffering a fractured leg and shoulder.
She remained there until her death.
A Metropolitan Police spokesman said a post-mortem examination showed Mrs Caddock died from acute peritonitis caused by her injuries.
