Police in London have released an image of the newborn girl abandoned in an east London park as freezing temperatures and snow hit the city.

The baby, who has been named Roman by nurses, was discovered in Newham by a woman walking her dog with her children as temperatures plummeted late last night and taken to a hospital in east London.

The baby girl was said to be in a stable condition this morning.

The Metropolitan Police said Roman was wrapped in a white towel which was put in the shopping bag and then placed on the ground next to a bench in the small children's play park.

No attempt had been made to hide her, they added.

Police said they were growing "increasingly concerned" for the welfare of the baby's mother.

Scotland Yard said she may be in urgent need of medical attention and urged her to contact police or the ambulance service.

Appealing directly to the mother, Inspector Shane Clarke of the North East Command Unit said: "It is really important that we know that you are safe.

"I would also urge anyone who has information that could help us to reunite this baby with her mother to come forward."

The force said it was called to reports of an abandoned baby at a park area close to Roman Road and Saxon Road at around 10.15pm.

Officers and the London Ambulance Service attended and the infant was taken to hospital.
