“Officers are becoming increasingly concerned for the welfare of the newborn baby which is everyone’s priority, and are asking for Constance and any members of the public who have any information to reach out to ensure they are safe and well.”

Mr Gordon is described as wearing dark clothing while Ms Marten, who has a southern accent, was wearing a burgundy coat. The baby was swaddled.

“Constance, I know this is an exceptionally hard time for you and you are likely feeling scared, but I promise that our number one priority is the same as yours – to keep your beautiful newborn safe.

“As you know, it’s really important that both you and your baby are assessed by medical professionals as soon as possible, so please make contact with emergency services or make your way to your nearest hospital, wherever that may be."
