Find the muggers who killed my wonderful mother

Lithuanian grandmother Ade Pukeliene, 57, died after being attacked by two masked men on a scooter just yards from home after returning from a night shift cleaning a bank.

As the thieves snatched her handbag - which contained only her Oyster card and work identification - she fell to the ground fracturing her skull. She died later at the Royal London Hospital in Whitechapel.

Today, four weeks after the attack in Emerald Close in Beckton, Mrs Pukeliene's only daughter, Gitana Skirmantas, 35, said: "I would like to ask anyone who has information or who saw anything to help find these two guys."

Mrs Skirmantas said: "We, as a family, loved my mother very much. She was a hard-working person and was respected by everybody who knew her."

Mrs Skirmantas said she had not come to terms with her mother's death. "I cannot understand that my mum is not alive any more. I think she's coming. I just wait at 6am to see her coming home."

Mrs Skirmantas said her mother had come to the UK two years ago to spend more time with her 10-year-old grandson, adding: "She helped everyone - me, my son. She looked after my son and she helped make food and sing songs. I'm not angry I'm just very upset and I can't understand why anyone would do anything to my mum.

"I didn't understand what had happened at first. My husband called for me and he said that she had collapsed. I thought she must have had a heart attack and I couldn't understand that someone had attacked her."

Police today stepped up the hunt for the killers by releasing a photograph of Mrs Pukeliene.

Detectives believe the attackers may have escped on the scooter which had no numberplates through Beckton District Park.

They are keen to talk to anyone who was in the park at about 6.50am on Thursday 28 February.

Detective Chief Inspector Carl Mehta said: "This park has a number of exits and it is possible that the riders escaped along a neighbouring street or the A13."

The suspects are described as black, between 5ft 8ins and 6ft tall and in their late teens or early twenties. Anyone with information should call 020 8345 3734 or Crimestoppers anonymously on 0800 555 111.
