X Factor judge Rita Ora has been warned she could be the latest victim of professional burglars who are believed to be behind raids on a number of north London homes, it has been reported.

Jewellery, cash and electrical goods are understood to have been taken when thieves broke in to the singer's six-bedroom semi-detached house in the early hours of November 28.

Just a week later, some £500,000 worth of valuables was stolen from Simon Cowell's £10million mansion less than three miles away.

Police are understood to be investigating the possibility that the same gang could be behind both crimes, and as many as six others in the area. 

It comes as Mr Cowell revealed he believes whoever robbed his house has 'inside knowledge' of the property.

A source close to Miss Ora told the Sun that the 25-year-old pop star has been ' very shaken' by the crime.

The source said: 'Thankfully, Rita wasn't home at the time, but a family member was sleeping upstairs so it could have been so much worse if they had been disturbed.

'They called the police who arrived after 5am after they found out that cash, jewellery and electrical goods had been stolen.

'The police have told Rita she needs to look seriously into the possibility that this was an inside job and could be connected to a number of burglaries in the area, including the one at Simon's house.' 

Last week Mr Cowell, 56, admitted he had feared for his son's life when burglars stole £500,000 worth of valuables from his family home in an overnight raid.

The music mogul said he and partner Lauren Silverman, 38, rushed to check on baby Eric when they learned of the break-in in the early hours of the morning on Friday 4.

Cowell said it is 'frightening' that someone has been in their home, but said it 'could have been worse' as no-one was hurt.

Last night he told the Daily Mirror that he believed the culprit had 'inside knowledge' of his property as the intruder knew how to avoid the bedroom where he and Ms Silverman were sleeping.

He said: 'He got up to the first floor and there were two doors, one to my bedroom and one to my bathroom, which leads to a dressing room where the safe was.

'So he could have walked into my bedroom. Instead, he chose the other so he went through the bathroom.'  He added that it 'creeps' him out to know that someone was 'three feet away'.

Earlier this week, Mr Cowell branded security guard M'Bathonha Mendes a 'hero' after he chased down the thieves and recovered some of the stolen jewellery and his passport.

Mr Cowell promised Mendes a Christmas bonus but said he will fire his bodyguard, who was totally oblivious to the theft as he was 'in the toilet'.

Cowell mentioned the burglary on last Saturday night's X Factor, joking that Reggie 'N' Bollie's song Locked Away was 'very appropriate'. 

Last week, a neighbour claimed there had been eight burglaries in the area over the past three weeks. 'People here are locking their internal doors,' they added.

'The culprit has been spotted a few times – he is 6ft 4in with dark skin. On one occasion he got in through the dog flap.'

Police have confirmed there have been at least three burglaries on three streets around Cowell's home since November and they were investigating the possibility that they are linked. 

Speaking about the break-in at Miss Ora's house, a Scotland Yard spokesman said: 'Police were called to an address at 5.54 on Saturday, November 28, to reports of a burglary. 

'An investigation is under way. No arrests have been made.'
