Mounting unprecedented security, Delhi Police today expressed confidence of a trouble-free Commonwealth Games and asserted that security norms would be applicable to everyone without any discrimination. Thousands of armed personnel have been deployed across 41 Games-related infrastructure, including 12 competition venues, while Indian Air Force will provide air cover to thwart any terror attack. “This is the security arrangement laid down after considerable thought, re-thought, examination and re-examination looking for loopholes,” said Delhi Police Commissioner Y S Dadwal, noting that it was a “moment of great challenge” to ensure security for the event.
