Access to the Parliament complex – a particularly high-profile issue after last week’s security breach – will now be guarded by the Central Industrial Security Force, or CISF, the government said in a notification issued Wednesday.

The CISF will displace Delhi Police, which will continue to protect the exterior perimeter – as the agency in charge, and will take over all related responsibilities, including frisking entrants.

Security within the complex will continue to be the responsibility of the Lok Sabha Secretariat.

The change will be enforced after a detailed security survey of Parliament, interior and exterior, that was ordered by the Home Ministry, and follows a security breach last week.

According to the CISF website, the force provides “integrated security cover to sensitive public sector undertakings”. At present it guards over 350 such locations, including airports and nuclear facilities.

On December 13 two men gained access to the Lok Sabha’s visitor gallery via passes issued by a BJP MP’s office, and popped yellow smoke canisters inside the chamber, triggering a massive security scare. These were slipped past Delhi Police’s physical checks in cavities cut into custom-made shoes.
