A Russian businessman linked to the poisoning death of former security agent Alexander Litvinenko said Tuesday he had been released from a Moscow hospital, where he reportedly was being treated for radiation exposure.
Andrei Lugovoi, who was questioned last month by Russian and British investigators, told The Associated Press that he was out of the hospital and was "resting," but did not elaborate. He said he would make no further comment until Sunday.
The Interfax news agency said he had been released late last month.
Litvinenko's death Nov. 23 in London sparked an international furor, after doctors determined he had been exposed to highly radioactive polonium-210. Days before his death, Litvinenko accused President Vladimir Putin of ordering his murder.
A Kremlin critic who lived in exile in London, Litvinenko fell ill after meeting with Lugovoi, Russian businessman Dmitry Kovtun and another man at a London hotel bar several weeks before his death, reports AP.
Lugovoi and Kovtun both of whom are also Russian ex-security agents had reportedly been contaminated by radiation and were undergoing treatment in Moscow. Kovtun's whereabouts were not immediately known.
British police say they are treating Litvinenko's death as a murder and have conducted investigations in both London and Moscow. Around a dozen London sites have been tested for traces of the rare element.
Scotland Yard detectives joined Russian prosecutors in Moscow last month to interview the two men.
The head of the Voronezh region, Alexander Gusev, confirmed the death of Major General Vladimir Zavadsky.
