A picture of Jasem Emwazi has emerged which suggests he is a conservative Muslim who shielded his children from Western culture.

Meanwhile his daughter’s former boss revealed how he had been aggressively confronted by Mr Emwazi after he was forced to sack her.

Mr Emwazi is now believed to be in hiding in Kuwait after his 26-year-old son Mohammed was last week identified as the masked Islamic State butcher who has fronted horrific hostage execution videos.

Details of his 25-year-old daughter were revealed by her former employer who said she was forced to move from Britain back to Kuwait against her will and made to wear an Islamic headscarf.

Despite growing up in London, she ‘knew nothing about life’ and did not understand references to celebrities, such as reality TV star Kim Kardashian, popular films, cars and brands of alcohol, he said.

Mr Emwazi, 51, said by a family friend to be a former Kuwaiti police officer, was a member of the ‘Bidoun’ group of stateless people denied citizenship by countries in the Gulf.

He and his family applied to become Kuwaiti citizens but were turned down after facing allegations that they collaborated with the Iraqi army during the seven-month occupation, Kuwait’s Al Qabas newspaper reported.  

Mr Emwazi then took his wife and his children, including Mohammed, to live in Britain in 1993. They settled in the north-west London suburbs of Maida Vale and Queens Park.

Last night it was revealed that Mohammed Emwazi worked as a top salesman for a Kuwaiti IT company aged 21. His former boss told the Guardian that he was ‘the best employee we ever had’.

‘He was very good with people. Calm and decent. He came to our door and gave us his CV,’ he added.

Emwazi earned 300 Kuwaiti dinars (£657) per month, plus 50 dinars (£109) expenses, and was promised 5 per cent commission on business he brought in.

During his time at the company in Kuwait City he requested time off to travel to London on two separate occasions. He left for good in April 2010. 

Soon after, counter-terrorism officials in London detained him and prevented him from returning to Kuwait.

His father is now understood to be in Kuwait with other members of the family. The Kuwaiti security services are said to be monitoring them around the clock. 

They spoke to Mr Emwazi on Saturday night, Channel 4 News reported. Contacted by phone yesterday, he said in a troubled voice: ‘Yes, I am Mohammed’s father. 

'I am sorry but I don’t want to talk to the media.’

‘Sometimes she used to cry. I remember she complained she didn’t want to be in Kuwait but her father was forcing her to be in Kuwait,’ he said.

‘She said she never felt at home here. She wanted to be in London. She was staying in her uncle’s house. She was saying that her uncle’s house didn’t make her feel comfortable.’

Mr Zubaid added: ‘She didn’t know the simplest things like which movie won an Oscar this year, or what car that was.

‘She didn’t know famous actors, or even what a bottle of Johnnie Walker whisky was. One time she asked, "Who’s Kim Kardashian?” She was sheltered in that way.

‘This is not what you would expect from someone who has grown up in London. Maybe the family forced her to lead quite a sheltered life. 

'I definitely got that impression.’ After eight months, Mr Zubaid decided to end her employment because she was struggling with the work.

Two weeks later, he learned she had complained to the Kuwaiti Ministry of Labour about her treatment. 

Then she turned up at the offices with her father, who demanded that she should be paid three months’ salary as compensation for losing her job.

Mr Zubaid said: ‘The father said, "I will not let her work for a man like you”. He was such a rude person. I almost hit him – I pushed him out. 

'We let her on to our staff and gave her a chance. 

'We even bought her an airline ticket for England. We went through a lot of trouble for her.'
