A top scientist who had a sickening stash of 245,000 child abuse images and sent fake poison to Theresa May has been jailed.
Dr Christopher Doyle, who once worked as a Cambridge University researcher, sparked a counter terrorism investigation when he sent Theresa May a picture of her beheaded when she was Prime Minister.
Within an envelope marked c/o The Nazi Party, the twisted scientist sent an angry pro-Russia rant and a mysterious white powder, thought at the time to be poison.
The 54-year-old’s letter was intercepted before it reached his target and the substance was fond to be harmless.
The former neuroscientist, who at one time worked at Porton Down, the government’s top secret lab, denied sending a substance intending a person to believe it was noxious.
An during a bizarre trial, Doyle, of Widnes, told a jury he didn’t include the power and was being set up as part of a MI5 conspiracy, the Liverpool Echo reports.
The pervert said he tried to "live every day as Jesus wanted him to" as he insisted he was part of a wider hoax.
But prosecutors told the court that police found a haul of child abuse images when they searched his flat.
He was jailed on Thursday for two years and ten months, and ordered to sign on to the Sex Offenders register.
In a dramatic twist to the case, officers said they found 245,505 images on the paedo’s computer.
Among the findings were snaps and videos of naked children in “sexual poses”.
Doyle previously admitted downloading the files – of children as young as six – but suggested to jurors many of them were legal and actually “beautiful and artistic".
A jury at Liverpool Crown Court found him guilty over both the fake poison stunt and the sick images.
Judge Anil Murray said: "This was a serious offence intended by you to induce fear of danger to human life."
During the trial, Joe Allman, prosecuting, said Doyle's letter to the PM was diverted to a screening facility in London on April 5 last year, the Liverpool Echo reports.
Specialist police said the envelope was stamped March 28 at Warrington Mail Centre and a mixed DNA profile on the stamp pointed to Doyle.
His letter included a poster of the then PM decapitated, from satirical French magazine Charlie Hebdo, along with the word 'Pravda' in Russian, and pictures of ex-Soviet leader Vladimir Lenin.
Within a second envelope was a cartoon of Alexander Litvinenko, who died after he was poisoned in London in 2006, and a volatile message criticising the MP's policy towards alleged Russian involvement in the Salisbury poisoning.
Doyle admitted he wrote to the then Prime Minister but denied putting any powder in his envelope.
He tried to convince jurors that he was being framed as part of an MI5, or MI6, conspiracy.
Doyle said he believed the government had opened his letter, were angered by what he had written, and planted the powder.
Jurors were told that Doyle was convicted of three counts of malicious communications in 2010, after sending cards to Marie Stopes family planning clinics in Leeds, Liverpool and Birmingham in 2009.
They featured pictures of aborted fetuses and a message reading: "Abortion is murder - how can you be outraged about the murder of Baby P and James Bulger but ignore the murder of unborn babies?"
Doyle, who insisted he didn't find them malicious and tried "to live every day in a way Jesus would want me to", said he was ashamed of his Category C indecent images, which included 188,540 videos.
he claimed they were “completely non sexual” and some were drawings by famous artists.
He later conceded in court that some pictures “crossed the border of indecency” and he said he had confessed to a priest.
Mark Pritchard, defending on Thursday, said no buildings had to be evacuated as a result of his client's stunt as a screening operation worked as was intended.
Mr Pritchard said Doyle had "genuine remorse" for the indecent images, but was still coming to terms with his offending.
He said: "The defendant suffers from bi-polar affective disorder and has essentially been living with agoraphobia, barely leaving the house, since 2013 following the death of a close friend.
"He is a man who has gone from being a successful research fellow at Cambridge University to living in almost isolation.
"He's been in a bubble of the pro-Russia Facebook groups to which he's been a member and to which he's ultimately created himself."
Judge Murray said the scientist sent the fake poison at a time when "the issue of poisoning was high in the nation's consciousness".
He said Doyle eventually accepted the images were indecent at trial when faced with a description of them.
However, the judge said Doyle still denied that he had them because of a sexual interest in children, which he could not accept, adding: "I'm sure you had them for your own sexual gratification."
Judge Murray said the letter was "sophisticated enough to cause the fear you wanted to cause" and Doyle was a "highly intelligent man" who had not acted in the "spur of the moment" and had "full insight" into what he was doing.
Jailing Doyle for 34 months - two years and 10 months - and also ordered him to sign on the Sex Offenders Register and to comply with a Sexual Harm Prevention Order for seven years.
