A lying fantasist posing as a billionaire who actually lived as a lodger in Sussex seduced a bank worker half his age – and then humiliated her through a campaign of harassment.

John Bond, who posed as the heir to a Swiss watch-making fortune and styled himself Dr Jonathan Le’Soux, has now been jailed for two years four months.

Cardiff Crown Court was told Bond, of Hurst Road, Eastbourne, used his glamorous alter ego to dupe both a 29-year-old bank worker from Cardiff and a 45-year-old teacher from Sussex.

Bond, who claimed he attended school with Jeremy Clarkson, told the younger woman he would buy her breast implants and persuaded the older woman from Sussex to change her name, told her to dress “more sexy”, promised make her a director of a language school he said he was opening in Brighton.

But then he said he had checked out her previous sexual partners and found one was HIV positive.

He convinced her she must be too, even after tests she had proved negative, and phoned her school in Sussex, posing as a concerned parent saying she was moonlighting as a prostitute.

She was so embarrassed she left the school where she was head of department, taking a drop in salary.

He gave her gold BMW car but the court heard he had got it from a disabled woman he was lodging with by telling her it could be used for a charity he was setting up.

The disabled woman also gave him her £600 mobility scooter after he claimed to know a young woman with a spinal injury who couldn’t afford one herself He hoodwinked the Cardiff bank worker after she applied for a personal assistant’s job he advertised with a £300,000 salary and a Porsche.

Telling her he was involved in the fashion industry and knew Formula One drivers, Bond invited her for an interview in Brighton.

Huw Evans, prosecuting, said: “He was 57, she was 29 - he excited her with the job promise and impressed her with apparent displays of wealth.

“He said he was off to Monaco, that he would pay for a Porsche and also for her to have breast implants.

“He even told her that in Cardiff they had been spotted together and he’d had to take out an injunction to prevent the press from publishing pictures.

“She believed he was a powerful man who could do anything.”

When she received an e mail claiming to be from “his PA, Millie”, saying her lover was critically ill in hospital with a sexually transmitted disease, she had no idea he had sent the message himself.

The court heart that a vast number of other messages which followed purporting to be from his “company”, had all been sent by Bond.

His younger victim was forced to have embarrassing tests in a local clinic and send him the results.

A later message warned she was being watched and threatened legal action until she sent him a list of all her previous sexual partners.

Eventually, “distraught and frightened” she contacted the Samaritans and eventually, “at her wits’ end”, went to the police.

Describing her ordeal, the woman said she had been left devastated.

She was particularly upset that he contacted her bank, pretending to be a journalist investigating what he said was her connection with a sexually explicit calendar.

And she said she also found her face on adult dating sites without her consent.

Jailing Bond, who had convictions going back 20 years, Judge William Gaskell said that he had degraded and humiliated the 29-year-old, causing utter misery.

After humiliating the young bank worker, Judge Gaskell said he then sought to destroy the life of a teacher who was also taken in by him and “became completely compliant to his demands”.

In court he pleaded guilty to harassing the bank worker with intent to cause fear, harassing the teacher and two counts of theft.

Jailing him, Judge William Gaskell said: “You caused distress, anxiety and fear by insinuating yourself into their lives and your whole purpose in seeking the (Cardiff) contact was to secure sexual contact with her.

“You frightened and intimidated her, all for your own apparent pleasure and there is clearly a sadistic element to your behaviour.”

A five year restraining order imposed will keep him a away from the victims.

Before he was led away to the cells, the court heard his latest claim was that he had the early onset of Alzheimer’s, something the judge described as ‘nonsense’.

He was also said to have a fiancée, a woman who knew his past and was waiting for him.

“If she wants to have him back, she can have him,” Judge Gaskell told lawyers.
