The alleged torture of Redbridge prisoners Suneet Jeerh, Grant Cameron and Karl Williams was “raised” during last week’s state visit from the president of the United Arab Emirates – but no investigation has been announced.

The three men, of Ilford and Wanstead, were jailed for four years the day before Sheikh Khalifa bin Zayed Al Nahyan arrived in the UK.

They denied all charges but were found guilty of consuming synthetic cannabis after more than nine months in prison in Dubai.

Mr Jeerh, 25, Mr Cameron, 25, and Mr Williams, 26, said they were tortured by police with beatings and electric shocks after their arrest.

Ahead of the visit, Prime Minister David Cameron said he would raise “concerns” with the president.

He added: “We continue to press for evidence for a full, impartial and independent investigation into the allegations.”

But the only agreements signed following meetings last Wednesday were on the recognition of qualifications, tackling sexual violence and a “dialogue of values”, including fighting extremism.

Foreign Secretary William Hague said: “I am pleased that through agreements signed we have a new forum to share ideas and foster a better understanding between our two countries across a range of issues, from human rights to shared security challenges.”

The Foreign Office said the UAE government would have to announce any investigation into the torture allegations but the embassy has not yet responded to the Recorder’s request for a comment.
