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.
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.
The parents of Ashya King said they took him out of a hospital to seek proton beam treatment which is not available under the NHS.
