Pakistan-based terror group Lashker-e-Taiba had managed to get forged passes issued to journalists and sponsors for the World Cup final at Mumbai's Wankhede stadium, prompting security forces to take extra care while checking their antecedents.
Alarm bells rang when a foreign intelligence agency conveyed to Indian security agencies that it had information that LeT militants managed some passes and might try to enter the stadium posing as journalists or sponsors.
Sources said the Centre shared the information with Maharashtra government and other agencies concerned, leading to deployment of additional security forces and NSG commandos.
CISF personnel were deployed to manage all entry and exit gates at the Wankhede stadium so that no unauthorised person can enter the venue with forged passes, they said.
The Home Ministry had also sent an Additional Secretary to Mumbai to take stock of the security arrangement there.
Sources said as per the security plans, anti-aircraft guns were strategically put in place. A sizable number of NSG commandos and around 400 central paramilitary personnel assisted Mumbai Police to ensure foolproof security.
All air bases near Mumbai, Indian Navy and Coast Guard were put on high alert to ensure security in the air and sea during the match.
Quick Reaction Teams and women personnel of CRPF were also stationed at vital locations in and around the stadium to respond to any exigency.
