The husband of a female prison guard who has gone on the run with with a Syrian rapist fears they will go to Syria.

Vasili Magdici, 25, has revealed how his estranged wife, Swiss prison officer Angela Magdici became fascinated with Syria and started reading the Koran before helping her asylum seeker lover break out of jail.

Police say 32-year-old Mrs Magdici freed Hassan Kiko, a Syrian migrant jailed for raping a schoolgirl, from Limmattal jail in Dietikon, Zurich, this week.

Kiko is a serial sex offender who was jailed for raping a 15-year-old schoolgirl and the attempted rape and sexual assault of a 19-year-old woman, MailOnline can reveal.

Mr Magdici told MailOnline: 'She was suddenly very close with a woman from Turkey, she became her best friend and she was learning Turkish words.

'I am worried she might try and go to Turkey, and from then on go to Syria.'

Mr Magdici, who married his wife in 2014, said he noticed a change in her about five months ago and suspected there was another man in the picture.

'I was there when she got an SMS in Arabic and her best friend was asked to translate it as quickly as possible,' he said, explaining he now believes the message was from Kiko.

One week before the pair split, he discovered that his Catholic wife had started reading the Koran.

Mr Magdici said: 'I only know the Bible, I had no idea why she suddenly had interest in the Koran.'

He added that three months ago she had been glued to the television while watching a documentary about Syria and did not want to sleep afterwards.

Then she simply vanished from their shared flat in Dielsdorf and he believed she moved in with her best friend. The couple had married in 2014 after meeting at a Thai boxing event three years ago.

In an interview with the Swiss media, he said: 'I loved her, and I wanted to have children with her.

'But then three months ago she told me she wanted to split. She moved out of the house when I was away, and took everything with her.

'Friends helped and I knew nothing about it until I returned.'

Convict: Hassan Kiko was granted asylum in Switzerland in 2010 after claiming he was imprisoned by Bashar al-Assad's regime and went on to get a job as a hairdresser

Kiko arrived in Switzerland in 2010, and in 2011 he was living in an evangelical church community where he and a friend spoke to local media about their difficult lives.

Kiko, pictured with his Kurdish friend Hasan Ramadan, spoke about his life in Syria, explaining: 'Syrian military officers in uniform were constantly mobbing and victimising my Kurdish friend.

'I wanted to protect him because we came from the same village, and as a result of that I ended up in jail for three months.'

He fled his country and a month later managed to cross the Turkish border and ended up in Switzerland.

He said: 'It was a hard time. I was very scared, and didn’t know whether I would survive this ordeal.'

Kiko said his parents were in Turkey and had not travelled any further after fleeing the Assad regime. He said he was searching for a job as a hairdresser, having been trained to cut hair in Syria.

Speaking about his new life, he told Thurgauer Zeitung he avoided the swimming pool, adding: 'Cooling down in the pool is not a thing to do, there are too many loosely-clothed women and in Ramadan we need to avoid that.'

Just months after arriving in an asylum centre, then 23-year-old Hassan invited a 19-year-old Swiss girl back to his accommodation, offering to cut her hair for free.

He then held a sharp object to her throat and forced her to perform a sex act on him and he then did the same to her.

Lovers: Angela Magdici had worked for the prison since 2013, but bosses said they were totally unaware of her relationship with Kiko

In June 2014, a court in Munchwilen sentenced him to 42 months for the attack. He appealed the sentence and as a result was not jailed immediately.

His conviction and sentence was confirmed by the High Court in Thurgau in mid-January but before that he had attacked again, this time raping a 15-year-old in Schlieren.

He met the victim in a shisha bar and told her to sit with him as he felt unwell. But when she followed him into the car, he began to kiss and fondle her.

She tried to push him away, asked him to stop and insisted on going back into the club, but he refused to let her go.

He took off his trousers and forced himself upon her, raping and then forcing her into an indecent sex act before letting her go.

He was jailed for four years in November 2014 after being convicted of raping the 15-year-old.

Pictures uploaded to Kiko's Facebook page show him posing for topless selfies in front of mirrors at a gym.

The breakout happened at midnight when the female prison officer waited until a male colleague was asleep before freeing her lover.

Prison guards said they had no idea a relationship had developed between the two.

The prison's director, Roland Zurkirchen, said: 'As supervisors, we need to maintain a professional relationship but sometimes it is necessary to speak in confidence with inmates.

'This is part of building a professional relationship and is part of everyday life.

'But supervisors should also keep the proper distance, which in this case did not happen.'

Police say that this was professionally planned and the two fugitives may already have left the country after escaping.

They say evidence so far indicates that the two had driven off in a black BMW X1 with the number plate ZH 528 411 and that they were headed to Italy.
