There is no evidence to suggest anyone else was involved in the death of Russian oligarch Boris Berezovsky, police have said.
The 67-year-old businessman was found dead at his Berkshire home on Saturday by a bodyguard, and specialist officers in chemical, biological, radiological and nuclear substances examined the property on Sunday before giving the all-clear.
Detective Chief Inspector Kevin Brown, of Thames Valley Police, said: “It would be wrong to speculate on the cause of death until the post-mortem has been carried out. We do not have any evidence at this stage to suggest third party involvement.”
Mr Berezovsky, who last year lost a multi-billion-pound High Court battle with Chelsea FC owner Roman Abramovich, was reportedly found dead in his bathroom after taking his own life.
On leaving the property, the paramedic who declared him dead had their radiation detector triggered, prompting the CBRN (chemical, biological, radiological and nuclear) experts to examine Mr Berezovsky’s country house, police said.
However, yesterday morning they confirmed the home at Titness Park, Mill Lane, Ascot, was safe to work in.
“An employee” of Mr Berezovsky, believed to be the bodyguard, had called for the ambulance shortly after 3pm on Saturday after forcing open a bathroom door and finding the oligarch dead on the floor.
Scenes of crime officers carried out a forensic examination.
In an interview with Forbes Russia magazine on the eve of his death, Mr Berezovsky said he had lost “meaning” from his life and wanted to return to Russia.
