The body of a newborn baby girl who went missing with her mother from hospital in the UK has been found by police.

Zaani Tiana Bevan Malbrouck was discovered in the same area of Avon Gorge in Bristol where her 30-year-old mother Charlotte Bevan's body was found by police last night.

An investigation is now being launched into the care both the mother and newborn received at Bristol Maternity Hospital.

The 30-year-old left the hospital between 8.30pm and 9pm on Tuesday night with her four-day-old baby girl, Zarnee Teanna.

CCTV footage showed her wearing hospital slippers and with her baby in her arms wrapped only in blankets.

The baby's father Pascal Malbrouck told a news conference on Wednesday that he was very concerned about her as she had suffered from mental health problems.
