15 held after BB compound invasion Fifteen protesters were being held after fathers' rights campaigners stormed the Celebrity Big Brother compound. The group Fathers 4 Justice said members who wanted to become "superhero housemates" entered the compound at Elstree Film Studios, Borehamwood, Hertfordshire, on three sides while a firework display diversion drew security guards towards the main gates. Police said that, with the help of a helicopter, 15 people - 13 men and two women - were arrested in the vicinity of the compound, on suspicion of conspiring to cause criminal damage. The group said the raid "was just the start of their General Election campaign which will target the Labour Party, other high-profile events and the disruption of activists' trials which start next Tuesday at Southwark Crown Court". A spokesman said: "Protesters had packed an F4J goodie bag for the housemates including a bottle of Diet Coke, a bottle of vodka, a large bar of Cadbury Dairy Milk chocolate and a pack of Mates condoms. "Once over the perimeter, protesters faced rottweilers, security guards in Land Rovers, police officers and a police helicopter with heat-seeking imaging equipment, though some protesters evaded detection for over an hour. "F4J wanted to raise awareness of the risks posed to young unmarried men who watch Big Brother and who might become fathers but are not aware that they have little or no rights in law to protect them." The group protests over the treatment of fathers in the family courts. F4J campaigners Jason Hatch and Dave Pyke sparked an embarrassing security breach on September 13 when they staged a protest at Buckingham Palace dressed as Batman and Robin. F4J national co-ordinator Mr Hatch said from his police cell: "Forget about Big Brother, this was big bother compared to when I scaled Buckingham Palace. The only saving grace was that we didn't come face to face with Sylvester Stallone's mum otherwise I would have had to give her my Batman mask." It appeared from live coverage of the Big Brother house that contestants remained asleep and unaware of the protest.
