AN SAS hero will ABDUCT Big Brother housemates tomorrow and try to “break” them under tough interrogation in the most controversial reality TV stunt yet.

Sun security adviser Andy McNab, who led the famous Bravo Two Zero patrol in the Gulf War, will stage a special forces-style raid at 5am.

The ex-SAS sergeant will storm in with a team of former comrades. Contestants will be dragged from their beds, blindfolded, bundled into a van and driven away.

They will then be interrogated to make them betray their fellow housemates by divulging secrets.

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 if anything goes wrong, Big Brother could be in trouble.

The Celebrity BB format was changed this year to Big Brother: Celebrity Hijack to avoid controversy like the Shilpa Shetty racism row.

In the new show — on digital channel E4 — celebs take turns to play the role of Big Brother.

Bosses, nervous in case traumatised housemates sue, only allowed the McNab plan after makers Endemol promised he will not go too far.

Andy, 48, knows how unpleasant a grilling can be. After being captured in Iraq he was tortured for weeks.

He 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 in the house. And if they spill the beans, other contestants will suffer.

Yesterday housemates were asked to volunteer for a special task. They know nothing more — apart from being reassured they will be safe.

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