Police have appealed for the mother of a baby girl to come forward after the newborn was abandoned in a plastic bag in a street.
The baby, believed to be between one and five days old, was found wrapped in a blanket inside a carrier bag outside a house in Stotfold in Hitchin, Bedfordshire.
She was discovered when the owner of the house in Kipling Crescent was locking up for the evening at around 9pm on Thursday.
The baby, who is fit and well and has dark hair, was taken to Lister Hospital where she was cared for overnight, said a Bedfordshire Police spokeswoman.
Officers from Bedfordshire Police were called to the house and inquiries and a search of the area were carried out throughout the night. Social services are now responsible for the baby's care until her mother can be traced.
Detective Inspector Jerry Waite, from the public protection unit, said he would like to speak to anyone who may have information about who the mother could be.
He said: "The baby is safe and well so our priority now is to find her mother.
"She must have been under great personal pressure in order to have felt she had no choice but to abandon her child. I would like to reassure her that our concern is for her wellbeing.
"She may need medical attention and will clearly be distressed so if she, or anyone who knows her, can tell us where she is, please contact the police."
Anyone with information is asked to contact the main switchboard on 01234 841212, text 07786 200011, or call Crime Stoppers on 0800 555 111.
