The grandmother of missing boy Ashya King has defended his parents, saying they were "wonderful" and had been left beside themselves by his illness.
Ashya, who was being treated for a brain tumour, was taken out of hospital by his family yesterday.
Speaking from her home in Southsea, his paternal grandmother Patricia King said she has last spoken to her son "quite a while ago", and did not know whether Ashya's illness was terminal.
Of her son, she said:
He's the most caring and wonderful father you could ever have. The kids love him. We are a very close family. He wouldn't have told me anything because he wouldn't want me to know anything in case I got involved in it all.
I knew he was seriously ill, we all knew that.
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.
