A newborn was left in a shopping bag on a residential block in London on Thursday, the Daily Mail reported.

A group of kids found the less than 24-hour-old abondoned baby girl on the third floor of an apartment building, suffering from the cold. The baby is recovering at a hospital and has been named Grace by the nursing staff.

Police are searching for the mother, who they fear could be in physical and mental distress, and are studying surveillance footage, the Mail reported.

"I would like to stress to anyone who hears this appeal, in particular the mother, that they should not hesitate to call us," Inspector Simon Rooke, from Lambeth Police, told the Mail. "We are concerned for the welfare of the mother and want to ensure that she is receiving the appropriate medical attention."
