A final appeal has been put out to find the mother of a baby boy who was dumped in a Tesco Bag for Life outside a church two years ago.
Police made the appeal to find the unidentified mother of the child, known only as Baby Peter, so she can help them bury her son.
The baby was found naked on a vicarage doorstep in Bramley, West Yorks, on November 23, 2016.
Paramedics performed CPR on the youngster and he was taken to hospital but was tragically pronounced dead.
However, a burial or cremation has not taken place while the hunt for his mother has continued.
Now detectives have made a final appeal saying that they have run out of leads and will now seek to make arrangements for his burial.
Police have stressed the mothers welfare continues to be their main concern but admitted they have exhausted all lines of enquiry in their efforts to find her.
They will now speak to the coroner about finally releasing his body for a funeral.
The discovery of Baby Peter was made outside the vicarage by Reverend Paul Crabb.
The vicars wife had returned home around 10pm the previous night, but did not notice the bag her husband later found beside their doorstep – with the slogan Its whats inside that counts written on the front.
Detective Superintendent Nicola Bryar, who has led the investigation, explained they had exhausted all lines of enquiry.
She said: Sadly we have now explored and exhausted all the available lines of enquiry without being able to identify the mother of this baby boy.
Throughout this investigation, her welfare has remained our main concern.
The immediate concerns we had for her health have lessened with the passage of time but we are still keen to trace her and make sure she has the help and support she needs after what has clearly been a traumatic experience.
The sentiments I expressed in a message on the first anniversary of his death a year ago remain exactly the same today.
She is not in any trouble with the police and there is still an opportunity for her to come forward.
Our discussions with the Coroners Office will include when her sons body can be released for a funeral.
That is something we would like her to be able to lead the arrangements for and to have the chance to say goodbye properly.
It is not too late for her to make herself known to me and I hope she might feel able to do that now.
Baby Peter, who was white, had been wrapped in a distinctive blue striped towel and a mens white 15-inch collar shirt from clothing firm Dunnes.
It was quickly established the infant had reached full term and the placenta was still attached.
It is believed he had been left at the church soon after he was born.
It remains a mystery whether it was the mother herself or someone else who left the baby on the steps of the vicarage, which is not easily identifiable to those unfamiliar with the area.
The infant appeared lifeless and was cold to the touch but was given CPR at the scene by paramedics before being taken to hospital, where he was pronounced dead.
A post mortem examination and further work by the pathologist was not able to ascertain the cause of death or whether he was already dead when he was left.
The tragic events prompted an outpouring of tributes from the local community, with flowers, teddy bears and notes left outside the church as news of the babys death became more widely known.
