Police have released an image of the newborn girl abandoned in an east London park as freezing temperatures and snow hit the capital.
The baby was discovered in Newham as temperatures plummeted late on Thursday night and taken to a hospital in east London.
The infant was said to be in a stable condition on Friday morning, while the photo showed she had been hooked up to an intravenous drip and monitoring equipment.
Meanwhile 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.
Anyone with information as to the whereabouts of the mother was asked to call police on 101 quoting reference CAD7825/31JAN or Tweet @MetCC.
