Here's the BBC News article: Radiation 'trace' at German homes
QUOTE
Police in Germany say they have found indications of radiation in two properties apparently used by a contact of murdered spy Alexander Litvinenko. Dmitry Kovtun, who met the former KGB agent on the day he fell ill, is being treated in hospital in Russia.
And in German via the Hamburger Abendblatt: Grosseinsatz Hamburger Polizisten und Scotland-Yard-Beamte untersuchen Wohnung.
Apparently the Russian authorities do not give permission to search the Aeroflot-machine Kovtun was flying in. I heard in the news about people living around the flat in Ottensen standing in the street in their dressing gowns discussing the case and having an eye on the efforts of the police.
