Litvinenko inqury: Radiation 'at highest levels where suspect stayed'
A police officer investigating the poisoning of ex-KGB agent Alexander Litvinenko has said the highest levels of radioactive contamination were recorded at the hotel where one of the prime suspects was staying.
Detective Inspector Craig Mascall told the public inquiry into Mr Litvinenko's death that traces of radioactivity were found throughout the Sheraton Park Lane hotel and in Andrei Lugovoi's room.
Mr Lugovoi, and Dmitri Kovtun deny any involvement in Litvinenko's death in 2006.
