Baby 'Elsa' less than an hour old when discovered in east London

Police say a baby found in a shopping bag by a dog walker was less than an hour old.

The new-born, temporarily named Elsa by hospital staff, was discovered in east London last night by a dogwalker who was alerted by the baby's cries.

Detectives said the dog walker kept the baby, who is believed to be black or mixed race, warm with blankets thought to have been left with the child.

She wasn't hurt in any way.

Detectives have appealed for the baby's mother to come forward, as they are "extremely concerned" for her welfare.

Chief Superintendent Simon Crick told GHR London

"We are extremely concerned for her welfare as she would have been through a traumatic ordeal and will be in need of immediate medical attention following the birth.

"Trained medics and specialist officers are ready to support her and we urge her to get in touch by phone or walk into the nearest hospital or police station.

"If you are the baby's mother, please know that your daughter is well. No matter what your circumstances please do seek help."

He said the mother will "absolutely" get support from the council and social workers if she comes forward.

It is not known whether she is local to the area.

Mr Crick said he was "extremely grateful" to members of the public who stayed at the scene, adding "your actions contributed to saving Elsa's life".

Temperatures dropped as low as minus 4C around London on Thursday night, the Met Office said.

Anyone who knows the mother is urged to contact police by calling 999 and using the reference CAD 6876/18 Jan.
