The father of missing child Ashya King has insisted he is not "neglecting" his son and urged police to "call off this ridiculous chase".
In a video uploaded to a YouTube account belonging to Ashya's brother Naveed, Brett says that the family went abroad to seek a procedure called "proton beam treatment" in the Czech Republic.
We decided to try and sort it out ourselves, but now we're refugees almost. We can't do anything. The police now are after us. The things we wanted to do to raise the money to pay for the proton beam [treatment], they have prevented it now ... Call off this ridiculous chase. We are not neglecting our son. He is in perfectly good health ... We just want t be left in peace.
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.
