Police have rejected criticism of their search for a five-year-old boy with a brain tumour removed from a UK hospital by his parents against medical advice.

Ashya King was found in Malaga on Saturday and his parents arrested, following an international search.

His father Brett King defended his actions in a video posted on YouTube, saying there had been a "ridiculous chase".

Hampshire Police said medical advice was that Ashya was in "grave danger".

The parents, it turns out, wanted their kid to be treated using a therapy not offered by the UK's socialized medical services.  Specifically, they wanted to use proton beam therapy rather than what the UK wanted to use (effectively gamma radiation.)
