Bioterror fears push 2010 Olympic's security budget to over $1.5 billion

Fears of a biological attack by terrorists have helped push the security budget for the 2012 Olympic Games to be held in London to over $1.5 billion.

Planners are preparing to stop a wide variety of potential threats, including an air attack or the kind of mass rioting seen across Britain in the summer. An unprecedented no-fly zone will be put in place to prevent a September 11, 2001-type attack, according to the Express.

“There are concerns around security,” a senior source familiar with the measures said, the Express reports. “Half the budget was for policing and half was ring-fenced to deal with threats such as biological attack.”

The security costs are now considered to be nearly three times their original estimates, despite pledges by Olympics minister Tessa Jowell and London Mayor Boris Johnson that costs would not continue to rise, according to the Independent.

British military units will be utilizing what is being described as Britain’s largest peacetime security operation. In addition, thousands of volunteers are needed to check both bags and tickets.

"An integrated, costed security plan is being produced, for ministerial agreement by the end of the year,” a Home Office spokesman said, the Independent reports. “This will cover strategic options for a range of security measures, including fraud and financial crime prevention and protection, counter-terrorism, identity assurance and personal protection."
