Gos is back

But the security alert turned out to be a false alarm when the suspect box discovered in studios near the house was found to only contain electrical equipment, said Hertfordshire Police.

Army bomb disposal experts examined the Elstree complex before declaring it safe on Friday night.

It is thought the alert began after the sniffer dog reacted to pyrotechnic residue in the stage area.

Elation

The housemates cheered when they were told they would have to evacuate the house, according to a Big Brother spokesman.

But their every move was watched on camera as they waited in a secure location elsewhere in the studios for three hours until the alert was over.

On their return, housemate Chef Gos Gosal said: "Can you believe it?

"We went behind the scenes! We were out of the house man!" .

Nush was also up for eviction

He was one of the three housemates who will now have to wait until Saturday to hear if he will be leaving the house for good as Friday's live eviction was postponed until 2100 BST on Saturday.

The 31-year-old, from London, was 1/7 favourite with bookmakers Ladbrokes to become the seventh contestant to leave the Channel 4 reality show.

Nush Nowak, 23, a student from Malvern, Worcestershire, had odds of 4/1 for eviction; while IT systems administrator Ray Shah, 25, of London, was 25/1 outsider to go.

The trio faced the public vote after getting the most nominations from fellow contestants on Monday.

Newcomer Lisa Jeynes, 35, from south Wales said in the diary room that the six remaining housemates were lazy and dull - and acted as if they were stuck in a "boring marriage".

Revealing her desire to win the �70,000 prize, she said: "I'm not in here to please them, I'm in here to win a game, as much as they don't know that."

She added: "I want to change the routine... even if it means making a fool of myself."

Critics have also accused this year's contestants of being boring, although producers insist they are happy with the fourth series and its steady ratings.

Anouska Golebiewski, 20, who became the first evictee from the UK house, is joining an Australian version of the show for a week.
