CBRN ruled out in fugitive Russian's death

CBRN experts investigating the death of Russian magnate Boris Berezovsky signaled that "nothing of concern" was found at the scene.

Berezovsky's Ascot, Berkshire, property, where he lived in exile, was found to be clean of potential CBRN properties, police said, according to Sky News.

Police in the United Kingdom are now investigating Berezovky's house to determine the circumstances of his death, which has now been labeled "unexplained." Initial reports suggesting that Berezovsky may have committed suicide were quickly refuted, RIA Novosti reports.

Berezovsky's body was discovered on a bathroom floor by an employee who had to force the door open and who then called the ambulance service.

"Police say the employee was the only other person in the Ascot home when the body was discovered," the Thames Valley Police said, adding that there is no evidence so far that a "third party" was involved in the death of Berezovsky, according to RIA Novosti.

Berezovsky's longtime friend Demyan Kudryavtsev said that Berezovsky suffered a heart attack, and a source close to Berezovsky corroborated that report, adding that he had recently received treatment in Israel.

Berezovsky was close with Russian fugitive and former KGB officer Alexander Litvinenko, who died from radioactive polonium-210 poisoning in London in 2006.
