The family of a British hotelier "unlawfully" jailed in Dubai since 2008 has called on the Metropolitan Police to probe alleged human rights abuses.
Ryan Cornelius, 68, has been held arbitrarily in the UAE for nearly 15 years, the United Nations ' Working Group on Arbitrary Detention ruled in June.
His relatives have now submitted a request to the Met's War Crimes Team over what they claim to be a "breach of both international and UAE law".
