SAS hero Andy McNab will abduct housemates on Big Brother: Celebrity Hijack and submit them to tough interrogation in what’s set to be the most controversial reality TV stunt ever.

Ex-SAS sergeant Andy, who led the famous Bravo Two Zero patrol in the Gulf War, will stage a special forces-style raid at 5am on Saturday, according to reports in The Sun.

Andy and his men will storm the house and housemates will be dragged from their beds, blindfolded, bundled into a van and driven away.

Those kidnapped will then be interrogated to pressure them into revealing secrets about their fellow housemates.

Victims will be manhandled, forced into stress positions, denied sleep, isolated from each other and subjected to sensory deprivation.

The stunt is a bid to boost viewing figures, which have slumped below 900,000.

But bosses only agreed to the McNab plan after makers Endemol promised is would not go too far.

Andy said: “The idea is to make them really believe the guys and I have taken over, the fun has stopped.

“That means taking them out of their comfort zones. Fear of the unknown is powerful. They’ll have trouble remembering this is a TV show.”

The ordeal will be shown live to the house. And if those kidnapped tell all, other contestants will suffer.

On Thursday, housemates were asked to volunteer for a special task – but they are still in the dark as to what the task entails.

But hardman Andy warned: “Big Brother asked me to do a job and I’m not bothered about the consequences.”
