A 10-year-old boy who vanished after a judge was told that he had cancer in his jaw and needed "urgent surgery" is with his mother in Poland and could be back in the UK by Christmas, a family court has heard.
Specialists had told Mr Justice Mostyn that the boy would die a "brutal and agonising death" within six months to a year if a tumour was not removed "very soon".
Concerns were raised in October when Mr Justice Mostyn heard that the youngster, who is Polish but cannot be identified, had disappeared.
Mr Justice Mostyn was told that there was evidence that the youngster had left his home in England with his mother and evidence that his father had boarded a ferry bound for France.
The judge - who analysed the case at hearings in the Family Division of the High Court in London - had urged the boy's parents to co-operate with doctors.
Lawyers involved in the case told another judge at another hearing in the Family Division of the High Court in London that the boy had been traced to an address in Poland.
