Ashya King, who is suffering from brain cancer, is in a stable condition in a hospital in Malaga, Spain, and has been visited by his brother Danny on several occasions, a hospital spokeswoman told ITV News.
The five-year-old's brother visited him twice yesterday and also this morning.
She also said that a police force is present in Ashya's room at all times with two officers guarding the child by court order.
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.
