Erovinkin reportedly had close links with Vladimir Putin
The report claimed Moscow held incriminating material on the US President, which it could use to blackmail him.
The Russian state-run RIA Novosti news agency said Erovinkin’s body was “found in a black Lexus and a large-scale investigation has been commenced in the area.
Erovinkin’s body was sent to the FSB morgue”.
It was later claimed he died of a heart attack. Christo Grozev, a Russia security expert, said he believes Erovinkin is the key person of interest Mr Steele refers to in the explosive memo.
Reports say Erovinkin died from foul play
He said Erovinkin was “the go-between between Putin and Sechin," adding: "One thing that everyone seems to agree – both in public and private sources – is that Erovinkin was Sechin’s closest associate.”
Mr Grozev told the Daily Telegraph: “I have no doubt that at the time Erovinkin died, Mr Putin had Mr Steele’s Trump dossier on his desk. He would, arguably, have known whether the alleged… story is based on fact or fiction.
"Whichever is true, he would have had a motive to seek and find the mole. He would have had to conclude that Erovinkin was at least a person of interest.”
