An exiled Russian businessman has been found dead at his house in south London late on Monday night.
Nikolai Glushkov, 68, was reportedly found by his family and friends at his house in New Malden, London and they summoned an ambulance at 10:46pm.
The cause for his death is not yet known but the Metropolitan Police have said that their counter-terrorism command unit is involved in the investigation 'as a precaution because of associations that the man is believed to have had'.
There is not currently any evidence to link this case to the events in Salisbury where former spy Sergei Skripal and Yulia, his daughter, are still in a critical condition after being poisoned, reports Sky News.

The police have not yet confirmed his identity officially, but said: "An investigation is under way following the death of a man in his 60s in Kingston borough.
"Whilst we believe we know the identity of the deceased, formal identification is yet to take place. The death is currently being treated as an unexplained."
Mr Glushkov was a friend of Boris Berezovsky, who was a vocal critic of Russian President Vladimir Putin.
Mr Beresovsky was discovered hanged at his house in Berkshire in March 2013; Mr Glushkov told The Guardian at the time: "I'm definite Boris was killed. I have quite different information from what is being published in the media.
"Boris was strangled. Either he did it himself or with the help of someone. [But] I don't believe it was suicide.
"Too many deaths [of Russian emigres] have been happening."

Glushkov had been in exile in UK since being released from prison in Russia in 2004. He was imprisoned for money laundering and fraud and served five years.
He gave evidence in a case in 2011 brought by Mr Beresovsky against Roman Abramovich, who he claimed had cheated him out of £3.2bn. The case was unsuccessful and the judge ruled in favour of Abramovich.
Beresovsky was also good friends with Alexander Litvinenko, who died after being poisoned with polonium 210 in 2006.
Glushkov was at the very top of the Russian embassy's 'fugitives from justice' list. He had been convicted of stealing $123m from Russian state airline Aeroflot in 2017. He was supposed to have been appearing at court on Monday morning but failed to show up.
