Police have confirmed the body of a baby girl was found on the shoreline at Bangor.

A post-mortem examination has been carried out following the discovery near Siliwen Road on Sunday afternoon as efforts continues to find the baby's mother.

Detectives say early indications suggest the newborn baby may have been in the water for up to a few weeks, but further tests are being carried out.

Meanwhile, authorities have made another direct appeal to the baby's mother to come forward, amid concerns about her safety and welfare.

Superintendent Llinos Davies from North Wales Police said: "Following the tragic discovery of a baby’s body in Bangor on Sunday 27 September, a postmortem has now been completed. We now know that she was a little baby girl."

"We understand that the mother may be fearful of coming forward but we urge her to make contact with us. I'd like to reassure her that her welfare and safety is our utmost concern."

"Anyone with concerns about a girl or a woman you think may have been pregnant or whose behaviour has been unusual or out of character over the past few months including withdrawing from friends, family or social ties, please contact us."

"Please do the right thing to ensure this mother gets the health support she needs. All names received will be treated with the utmost discretion and can be eliminated as the mother without delay."

"I understand that this is a terribly sad incident for the community and I am grateful for the overwhelming support and assistance that we have received so far."

On Wednesday, police said they were working with other partners at a fast pace to establish the circumstances surrounding the baby's death.

Officers remain at the scene of the discovery, where a cordon remains in place, while also receiving specialist advice on their investigation.

The Betsi Cadwaladr University Health Board (BCUHB) said their immediate concern remains for the mother's "health, safety and wellbeing".

In a fresh appeal to the mother on Thursday, Fiona Giraud, director of midwifery and women's services at BCUHB, said: "You may feel you have nowhere to turn, or that you cannot speak to anyone about what has happened. Please do not feel that you have to face this alone."

"We don’t yet know all the circumstances surrounding your baby's death, but what is important right now is that we find you, make sure you are safe, and ensure you receive any medical attention and support you may need."

"I am asking you personally, please take the first step and contact us. There are people to help you."
