Newport unassisted birth baby 'may have survived'
Detectives investigating the birth of a child at an "open-air birthing site" believe the girl may have survived.
A woman is believed to have given birth unassisted and outdoors in Penhow, near Newport, in October 2015 when between 27 and 35 weeks pregnant.
Officers have been unable to trace the mother but medical tests of her placenta, which was found at the site, suggest the baby could have survived.
Gwent Police has made a fresh appeal on the anniversary of the discovery.
Inquiries with medics, scientists, schools, social services and local residents have drawn a blank as to the identity or whereabouts of the mother or the baby girl.
Police believe the baby was born sometime between October 18 and October 19 2015.
"There may have been a very good reason for the baby being born under these circumstances and for the identities of the mother, baby and even the father to remain confidential," said Det Supt Ruth Price.
"But if those reasons were in any way connected to the mother being the victim of a crime or being under pressure or duress to conceal the birth, she and the baby may still need protection."
