The Central Public Works Department (CPWD) had floated a tender for additional security infrastructure for the Parliament complex, including security gadgets and bulletproof enclosures, on December 12, a day before the security breach in the Lok Sabha took place. The CPWD comes under the ambit of the Union Housing and Urban Affairs Ministry.
Two men jumped from the public gallery into the Lok Sabha chamber during Zero Hour on December 13, carrying what appeared to be gas canisters, which they spewed around the room before they were overpowered by MPs and handed over to security staff. Two others sprayed coloured smoke and shouted slogans just outside the Parliament’s premises. All four have been arrested under the Unlawful Activities (Prevention) Act, an anti-terror law.
