Just before 20:00, housemate Scott was informed in the Diary Room by Big Brother that all housemates were to go to the boys bedroom and remain there until further notice. Around 20:45, Hertfordshire Constabulary police force advised that all housemates were to be evacuated. Production staff and a camera crew entered the house, made them aware of the security alert and evacuated them. They were taken to a secure area on the perimeter of the studio complex, with high levels of security accompanying them.
