The 25-year-old was absent from the challenge in the Middle Eastern country, which saw the budding entrepreneurs tasked with planning corporate away days for international clients.
Reece previously revealed he was forced to pull out of the action and could not travel due to health reasons.
But an insider has claimed he was axed from the juggernaut reality series after consuming booze against producers’ wishes, leaving them ‘unimpressed.’
A source explained: ‘Reece was sent home and didn’t film in Dubai.
‘Producers were unimpressed when he had several alcoholic drinks on the flight even though he was told not to.
They continued to MailOnline: ‘Lord Sugar was obviously furious, he couldn’t believe someone would risk securing his £250,000 investment for the sake of a drink.
‘He later told the candidates in the boardroom that Reece had been eliminated from the process.’
Reece previously told Metro.co.uk that he believed he would have lasted longer in the competition had he continued.
He explained: ‘I would have loved to be standing there shaking his hand, accepting the £250,000,’ he began.
‘I don’t know if I would have won, but I certainly don’t think I would have been going anywhere anytime soon.
‘You can only do so much in that show, and I gave it my all, so if I got sent home for giving it all, I would have been happy for that.
‘But you know, I would have loved to have stayed a little bit longer! I just wanted to make it to the interview stage so that I can tell the world about my business!’
A spokesperson for The Apprentice said: ‘Reece was unable to continue in the process, this was discussed and agreed between Reece and programme-makers.’
The Apprentice continues on Thursday on BBC One at 9pm.
