Three British man found guilty of possession of drugs in Dubai have each been sentenced to four years in prison, according to reports.

Grant Cameron and Suneet Jeerh, both 25, and Karl Williams, 26, were jailed for possessing a quantity of a synthetic cannabis known as spice.

The men, all from London, were on holiday in the Gulf state in July last year when they were arrested after police found the drug in their car.

They claimed they were tortured by police following their arrest, alleging that they had guns held to their heads by police.

Mr Williams also said he had electric shocks administered to his testicles.

Tracy Cameron, Mr Cameron's mother, told Sky News that she had seen her son for two hours on Thursday.

She said he is being held in a maximum security prison in what are "quite harsh conditions", but that he has access to exercise.
