German police say they have found traces of a radioactive substance in a location linked to poisoned former Russian spy Alexander Litvinenko.
Police said Saturday they have found traces of radiation in a Hamburg apartment building associated with Russian businessman Dmitri Kovtun. He met Litvinenko in London on November 1, the day the former KGB agent become ill from radiation poisoning.
Kovtun has been reported to be in critical condition suffering from radiation poisoning. However, his lawyer denies the reports and says his client's health is satisfactory.
Litvinenko died nearly three weeks ago from what British authorities say was a lethal dose of the radioactive substance polonium 210.
In a deathbed statement, he accused Russian President Vladimir Putin of ordering his murder. Kremlin officials deny any involvement in Litvinenko's death.
