The public has been asked to help find three young boys who have gone missing in London.
High Court judge Mrs Justice Theis said that she had "very great concerns" for the welfare of 13-year-old twins Martin and Christopher Joyce and their 11-year-old brother Daniel and it is essential they should be returned to their mother's care.
"I urge anyone who has details of their whereabouts to give them to the police immediately. It is clear somebody must be caring for them and it is their duty to give information to the authorities and the police to ensure they are located."
The boys were brought to England by their mother, Mary Ellen, from the Republic of Ireland, where they live, to attend another brother's wedding, in November last year.
They stayed with their father Patrick in Peckham, south London, but were not returned as agreed following the trip and remained with him until May 15.
After Mrs Joyce issued proceedings, Mr Joyce was ordered to bring the children to court, but attended on his own, saying the boys did not want to go home.
When the police could not find the boys at their father's address and he said he did not know where they were, Mr Joyce was taken into custody and is now serving a six-month prison term for contempt of court.
After the children were found earlier this week, they were taken to foster carers while Mrs Joyce came over to collect them, and were on their way to a rendezvous on Tuesday when they absconded in Peckham.
