Radiation found in British Embassy

ITV: Traces of radiation have been found at the British Embassy in Moscow by the team probing the death of ex-Russian spy Alexander Litvinenko.

The Foreign Office confirmed an expert team has found small traces of radiation in the building but announced there is no risk to public health and the embassy is functioning as normal.

The news comes as Scotland Yard comfirmed they are now treating Mr Litvinenko's death as murder.

Yard officials have travelled to the Russian capital as part of their investigations.

Nine British detectives are planning to interview several potential witnesses in the case, including Andrei Lugovoy and Dmitry Kovtun who met Mr Litvinenko in London on the day he became ill.

However, Mr Lugovoy may be unable to speak to the UK team as he is believed to be in hospital undergoing a second test for polonium-210 - the radioactive substance which killed Mr Litvinenko.

Russia's chief prosecutor has said the team of men and women will be assisted in their investigation but made it clear his officials will be fully in control.

Meanwhile, a third man who met Mr Litvinenko on the day he was poisoned has been released from hospital after testing positive for polonium-210.

Italian academic Mario Scaramella was discharged from University College Hospital in London. He met Mr Litvinenko in a Piccadilly sushi bar on November 1 and allegedly showed him emails from a source warning the pair their lives might be in danger.

He denied any involvement with the death and blamed it on Russians who may not be under Kremlin control.

Yesterday it was announced traces of polonium-210 had been found at Arsenal's new football stadium.
