The Parliament complex has been closed to visitors following a major breach Wednesday afternoon, in which two men admitted to the visitors' gallery popped yellow smoke canisters and one made a run at the Speaker's Chair. Two others - a man and a woman - opened smoke cans outside the complex.
After the scare, security protocols were revamped, including allotting separate entrances to MPs, staff members, and the press. Visitors, when allowed back, will enter from a fourth gate. Issue of visitor passes has been suspended.
In addition, the visitors' gallery will now be encased in glass to stop people from jumping into the Lok Sabha chamber. Body scan machines, similar to those in airports, will be installed in Parliament.
Finally, the number of security personnel inside the House has been increased.

Sagar Sharma and Manoranjan had visitors passes that were granted on a request by BJP MP Prathap Simha's office. Mr Simha is the lawmaker from Mysuru. However, as the Congress' Karti Chidambaram, told NDTV such requests are routinely made to MPs, and it is the Parliament that issues the passes.

How 2 Men Evaded 4-Tier Security
The security process in use at the old Parliament building was overhauled after the terror attack that took place on this day in 2011. Two Pakistan-based terror groups carried out that attack, in which nine people, including eight staff members, were killed. The three-tier process then was upgraded to four.
The systems in place till this afternoon involved frisking of visitors and checking-in their belongings. Phones, bags, pens, water bottles and even coins were not allowed, and visitors also had to submit their Aadhaar cards. Only after this were they even given passes to enter the Parliament building.

Issue of passes also involves mandatory background checks. Prospective visitors must show a letter of recommendation signed by a MP; in this case that member was the BJP's Prathap Simha.
