Intruders break into Big Brother house

Security is being stepped up at the Big Brother house after two intruders broke in and confronted the contestants.

The men scaled two perimeter fences, got into the garden.

Once there they jumped on to the hot tub, scarcely unable to believe they had made it.

They cheered into the cameras: "We're in the Big Brother House."

They paid little attention to the housemates who had flocked to the garden to watch the commotion.

Show favourite Brian ran to the pair and challenged them, shouting: "What are you doing?"

Big Brother told the housemates to lock themselves inside before security guards escorted the men from the site.

The show's executive producer Conrad Green, said: "There are stringent security measures in place at the Big Brother house. These two young people were very enterprising to have managed to evade them all.

"As a result... We will be reviewing our security measures to ensure that this does not happen again.

"However this was a foolish undertaking and they were very lucky not to have been seriously hurt as the house is surrounded by razor wire and the security guards have dogs."
