Nikolai Glushkov was connected to Boris Berezovsky, who was found dead in 2013 and a friend of Alexander Litvinenko.

A Russian exile formerly associated with the late Boris Berezovsky was found dead in his London home Monday night.

According to the Independent, authorities say Nikolai Glushkov's death is being treated as "unexplained".

A spokesperson for the Metropolitan Police said its counter-terrorism command was leading the investigation “as a precaution because of the associations that the man is believed to have had”, but there was no immediate evidence of a link to the Salisbury nerve agent attack.

Glushkov was a close associate of Berezovsky -- himself a Russian exile -- after working for Berezovsky's LogoVAZ car company.

Berezovsky was found dead in 2013, having reportedly hanged himself in a bathroom; however, officials were unable to determine if the incident was suicide or foul play.

At the time, Mr Glushkov said he believed his friend had been murdered, telling The Guardian: “I don't believe Boris died of natural causes. Too many deaths [of Russian exiles] have been happening.”

Mr Berezovsky’s death is among up to 14 being reviewed by police and MI5 in light of the nerve agent attack on Sergei Skripal and his daughter in Salisbury.

Berezovsky also had a connection to former Russian spy Alexander Litvinenko, who died in the U.K. from polonium poisoning in 2006.

Litvinenko had also become close friends with Putin antagonist Boris A. Berezovsky, a Russian oligarch who publicly claimed that Putin was behind a wave of terrorism that led to his first election victory and resuscitation of Russia’s conflict with Chechnya. In 2016, ten years after Litvinenko’s death, the British government released an official reportand stating that Vladimir Putin probably approved the murder of Litvinenko. In 2013, Litvinenko’s friend, Berezovsky, was later found hanging at his ex-wife’s mansion.
