Police are "urgently" hunting for a mother and her newborn baby daughter who went missing from a maternity hospital last night.
Charlotte Bevan, 30, left Bristol Maternity Hospital between 8.30pm and 9pm with her four-day-old baby girl, named Zarnee Teanna.
She did not have a coat or shoes and is thought to have been wearing hospital slippers, while her baby was wrapped only in blankets.
A spokesman for Avon and Somerset Police appealed for anyone who sees Ms Bevan and her child to call 999 immediately.
"We are concerned for both Charlotte's welfare and that of her baby, and are urging Charlotte to let us know that she and her baby are all right," the force spokesman said.
Officers have been searching the city centre throughout the night and appeals have been put out to bus drivers and taxi drivers and those travelling into work on early shifts this morning to look out for Charlotte and her daughter."
Ms Bevan is described as white, around 5ft 8in tall, of average build with dark wavy hair.
She is believed to have been wearing a long black top and black trousers when she went missing from the hospital, on Southwell Street.
The force spokesman added that Ms Bevan "may appear confused and worried".
"Her baby is inappropriately wrapped for the cold weather in a blue and white striped and coloured blankets," he said.
Friends have described Ms Bevan's disappearance as "out of character".
Writing on Avon and Somerset Police's Facebook page, Isaac Jack McCardle described searching for mother and baby last night.
"I know her and her partner. This is out of character," he wrote.
"I was out on the streets with a friend for over three hours and searched almost every road, park, alleyway etc in the area as well as high streets and found nothing.
"We talked to a police officer who was patrolling in a car and told us she'd not yet been found. I was in a warm coat and now I'm back home and chilled to the bone so it is worrying.
"I really hope they are both safe and are all reunited soon. I do feel out of respect people should stop jumping to conclusions. They are a happy couple."
Mr McCardle responded to other users of the site who asked whether he had been able to locate Ms Bevan.
"I searched literally every road nearby. All the back streets, parks, behind local shops, hospital, Redland, Cotham and found no trace. I'm hoping/thinking she may have got some transport somewhere to a safe place?" he replied.
Mr McCardle said he had met Ms Bevan, from Bristol, once before and knew her partner "fairly well".
On November 19, Ms Bevan posted one picture of her smiling in a white lace dress and another in a patterned dress, with her pregnancy bump visible.
