In order to ensure foolproof security during the Commonwealth Games, the government has sanctioned Rs 330 crore for procurement of high-tech weapons and devices to counter any possible nuclear and biological attacks.

The fund has been alloted to purchase close circuit television cameras, different types of metal detectors, equipment for bomb disposal squads, devices to deal with chemical and biological attacks, armoured vehicles and various types of weapons.

The home ministry has given highest priority to the security of the fortnight-long sporting extravaganza which is scheduled to be held between October 3 and 14, 2010 here.

"All weapons and equipment will be procured and put in place well before the Commonwealth games begins. We will ensure that funds will not be a constraint in the overall security of the games," a ministry official said.

So far, there is no credible threat to the Commonwealth Games. But, government is taking all precautions as any attempt to target any sports person or official by terrorists may have international repercussion.

Apart from specialised commandos and regular police, IAF helicopters with commandos armed with snipers and assault rifles will be deployed to keep a hawk-eye vigil over Delhi during the Commonwealth Games.
