The last CCTV images of a 57-year-old widow who was murdered as she returned to her east London home after a night shift have been released.
The image shows Ade Pukeliene leaving her office at Canary Wharf
Ade Pukeliene was found on Thursday on a pavement in Emerald Close, near Canary Wharf, with head injuries.
Mrs Pukeliene, who worked as a cleaner, was taken to hospital but died later.
Officers believe she was attacked by two men on a scooter who robbed her of her handbag as she left Royal Albert DLR station.
No one has been arrested over the attack.
Mrs Pukeliene who was Lithuanian, lived with her daughter, son-in-law and grandchild, police said.
In a statement her daughter, Gitana Skirmantas, said: "We, as a family, loved my mother very much.
Police are looking for two men in connection with the killing
"She was a hard-working person and was respected by everybody who knew her."
Detectives said the two suspects fled on a gearless scooter from Emerald Close and onto the Becton District Park, close to the junction of Stansfeld Road, Canning Town.
Describing the murder as a "callous attack" Det Ch Insp 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 suspect vehicle, described as silver or light grey in colour with no registration plate, was last spotted at about 0700 GMT on Thursday morning.
The suspects have been described as black, about 5ft 8in to 6ft tall, aged in their late teens or early twenties.
They were wearing either hooded tops or hats and possibly had masked their faces with scarves.
Police added that the pair had been possibly waiting in nearby Jasper Road and Stansfeld Road up to 20 minutes before the attack.
