The Office of Public Information for Jehovah's Witnesses confirmed that the parents of missing boy Ashya King were followers of the religious movement.
We can confirm that the parents of Ashya King are Jehovah's Witnesses. However, we are not aware of the facts of the case nor the reasons for the family's medical choices, which are personal decisions.
There is absolutely no indication, as far as we are aware, that their decision is in any way motivated by any religious convictions. Jehovah's Witnesses are encouraged to seek the best medical treatment for themselves and their children.
Jehovah's Witnesses refuse blood transfusions on religious grounds but are open to other medical procedures.
Police said the family's religious beliefs were "irrelevant" at this point.
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.
