The parents of Ashya King have arrived at a Spanish hospital for a reunion with their sick son.
But the five-year-old brain tumour patient's father Brett claimed he would be stopped from seeing him for the first time since he and wife Naghmeh were arrested on Saturday.
Arriving at Materno-Infantil hospital in Malaga, Mr King said:
We have come to see him but they won't let me see him.
Portsmouth Council have made him a ward of court, so we don't have custody over him.
If I see him, then they will arrest me.
Ashya King's parents told the Daily Mail they fled the UK after being told NHS treatments would leave him with life-long disabilities.
The head of the police force which applied for a European Arrest warrant against the parents of Ashya King has now urged their release.
A British mother whose son's life was saved by proton therapy has told ITV that she defied NHS doctors' advice to pursue the treatment.
