British police and key organisations involved in the London 2012 Olympics yesterday launched tests to prepare for a possible terror attack on the event, the police officer in charge of Games security said.

“We recognise the terrorist threat could come from anywhere,” London police’s Olympic security coordinator Chris Allison told AFP, as he unveiled a series of exercises to test security, which will run over the coming year.

“It potentially is the biggest one for us,” he added, speaking at the Scotland Yard headquarters of the city’s Metropolitan Police.

The Olympics will see the biggest ever peacetime policing operation in Britain amid fears that terrorists could attack an event which will attract huge attention worldwide.

The government has earmarked €670 million for Games security.
