British Prime Minister David Cameron has intervened personally to help a 12-year-old boy who wrote him a letter last year pleading for help after his family allegedly took and kept him in Qatar under false pretences.

Adam Jones claimed he was "kidnapped" by his uncle after he visited Qatar with his mother, Rebecca Jones, in October 2009.

On the Bring Adam Home campaign website, Jones describes how members of Adam's late father's family made her sign documents, written in Arabic, that she could not read. The documents apparently allowed them to begin custody proceedings against her, and they then took her son.

In Adam's handwritten letter, dated May 25, 2011, he tells Cameron he is not allowed out and is being abused by his uncle's sons.
