Woman, 29, had to be admitted to a psychiatric hospital after being left distraught when she was duped out of $200,000 by Tinder swindler posing as Israeli 'Prince of Diamonds'

When Cecilie Fjellhoy matched with Simon Leviev on Tinder, she thought she had met the perfect guy.

Leviev, 28, told Fjellhoy, a 29-year-old Norwegian graduate student living in London, that he was an Israeli millionaire known as the 'Prince of Diamonds'.

Their first date included a trip on a private plane to Bulgaria, and they would exchange love notes over text, videos and voice messages. 

Soon into the relationship, Leviev asked Fjellhoy to open a line of credit in her name so he could pay his expenses and protect himself from his 'enemies'.

Fjellhoy quickly found herself swindled out of $200,000, leaving her so distraught she had to be admitted to a psychiatric hospital reported ABC's Nightline.

As it turned out, Leviev was really Shimon Hayut, a convicted conman accused of snaring Scandinavian women out of millions of dollars.

Leviev (left and right) said he had to travel constantly for work. The couple dated long-distance, sending texts, videos and voice messages over WhatsApp.

'I hate him, he's so horrible,' Fjellhoy told Nightline. 'I am just tired of crying about this, you know? It's just so painful. I just hate myself that I did this.' 

She said that she quickly fell for Hayut when they first met.

'This was the first time where I felt like: "Oh my god I really like him. And it seems that he really likes me back as well",' Fjellhoy said.

'He's texting and he's calling and he seems to really want to get to know me, and I think I feel a bit for that.'

Hayut told Fjellhoy that he had to travel constantly for work and that it was hard for him to visit her in London due to threats from working in the diamond business, reported Nightline.

The couple dated long-distance, sending texts, videos and voice messages over WhatsApp.       

The conman first asked Fjellhoy to take out a line of credit for him in her name just four weeks into their relationship, claiming that it was a security measure due to threats against him. 

He spent the money on plane tickets, hotels and dinners that were booked under her name to throw off suspicious 'enemies'. 

'One of the main reasons why he needed it was protection…he needed my name as a cover, he said,' Fjellhoy told Nightline. 

'I know it sounds crazy...[but] why would he have this giant guy with him if he didn't need the protection?'

The 'millionaire' turned out to be Shimon Hayut, a convicted conman who was swindling Scandinavian women out of millions of dollars. Hayut was arrested in Greece (left and right) and Israel wanted him extradited on charges of theft, forgery and fraud 

Fjellhoy said Hayut promised to pay her back but, as the weeks rolled by, her balance went up and up.

She claims that she filled out documents for an American Express platinum card per his instructions and he told her to file an income of £200,000.

The alleged conman assured her no one was going to check it.   

Fjellhoy told Norwegian news site Verdens Gang that she took the handsome young Israeli at his word. 

She took out huge loans for the card and claim Hayut was soon maxing out the plastic.

Hayut spent two million Norwegian krone ($224,220) in just 54 days and was racking up bills on paying for his two assistants, his bodyguard and flights across the world.  

'I had to be put into a hospital. Psychiatric ward,' Fjellhoy told Nightline.

'Because of suicidal thoughts because I thought my life was over, like I didn't see a way out,' she said. 'You've lost your boyfriend but he didn't just dump you, he never existed, he was never your boyfriend.'

Hayut was arrested in Greece in July following a joint operation between Interpol and Israeli police.

Israeli authorities have requested his extradition to his home country, where he has been wanted on charges of theft, forgery and fraud since 2011, the Times of Israel reported.     

He is also under investigation for fraud in the UK,  Sweden, the Netherlands, and Germany. 

Standing outside a police station, he claimed he would be a 'free man' within a month as he kissed a woman and told her that 'nothing she's read about him is true', Verdens Gang reported.
