The four arrested include Sagar Sharma and D Manoranjan, who used yellow smoke canisters inside Lok Sabha, and Neelam Devi and Amol Shinde, who burst red and yellow canisters outside Parliament.
The other accused are Lalit Jha and Vicky Sharma, both from Gurgaon. Jha reportedly shot videos of the other accused deploying smoke canisters outside and fled with their cellphones. He is on the run. Vicky Sharma allegedly sheltered the other accused. He and his wife have been detained. 
The Delhi Police’s investigation so far has found that all the accused were linked to a social media group named Bhagat Singh Fan Club, according to sources.
The accused met in Mysore about one-and-a-half years back and discussed how to go about the plan. Another meeting took place about nine months back when the accused planned their moves.
Sagar Sharma, sources said, came to Delhi from Lucknow this July. During that visit, he could not enter Parliament, but recced it from outside, carefully noting the security checks. To execute the plan for yesterday, the accused reached Delhi this Sunday. They put up at Vicky’s home in Gurugram.
Amol Shinde, it is learnt, got the smoke canisters from his hometown in Maharashtra. The canisters were distributed among the members of the group during a meeting at India Gate.
All the six wanted to go inside Parliament, but only Sagar Sharma and Manoranjan managed to get the passes, sources have told NDTV. The two entered Parliament at noon yesterday.
Shocking scenes were witnessed during Zero Hour in Lok Sabha yesterday when Sagar Sharma jumped out of the visitors’ gallery and into the chamber. He opened a yellow smoke canister and jumped from desk to desk in an attempt to reach the Speaker’s Chair.
As MPs overpowered and beat him up, Manoranjan too opened a smoke canister. He, too, was soon caught. Shortly before the scenes played out inside Lok Sabha, Neelam and Amol burst canisters outside, and raised slogans against “dictatorship”.
Delhi Police’s anti-terror cell is questioning the six accused. Lok Sabha Speaker Om Birla has reassured MPs about their safety and said a thorough investigation will take place. The huge security breach took place on the anniversary of the 2001 Parliament attack.

Hamas chief Ismail Haniyeh said Wednesday that any plan for post-war Gaza that does not involve the Palestinian militant group is just a “delusion”.

“Any arrangement in Gaza or in the Palestinian cause without Hamas or the resistance factions is a delusion,” said Haniyeh in a televised speech.

Haniyeh’s comments came a day after Israeli Prime Minister Benjamin Netanyahu said that he will not allow “the entry into Gaza of those who… support terrorism and finance terrorism”.

Haniyeh, however, said he was open for talks for ending the Israeli assault and “putting the Palestinian house in order both in the West Bank and the Gaza Strip”.

He said Hamas was ready for talks that could lead to a “political path that secures the right of the Palestinian people to their independent state with Jerusalem as its capital”.

The Delhi police said that the Parliament security breach was well-coordinated and meticulously planned over months by six people, five of whom are now in police custody. During questioning, the accused told police that the breach was aimed at drawing the government’s attention to various issues.

Sources said that the five accused have told police that they were upset with issues like unemployment, farmers’ troubles and Manipur violence. They say they used the colour smoke to draw attention so that lawmakers have discussions on these issues.

“They had the same ideology and hence decided to give a message to the government. The security agencies are trying to ascertain if they were instructed by anyone or any organisation,” an official said.

On Wednesday afternoon, as the Lok Sabha was holding a Zero Hour session, Sagar Sharma jumped out of the visitors’ gallery and into the chamber. He popped a yellow smoke canister and, in incredible scenes, jumped from desk to desk in an attempt to reach the Lok Sabha Speaker’s Chair.

He was overpowered and captured by MPs, several of whom then thrashed him. His accomplice – Manoranjan – remained in the gallery; he too opened a smoke canister, presumably to distract attention.

Two other protesters were caught releasing colour smoke from an aerosol canister on a road outside the Parliament.

While being taken away by police personnel, one of the protester told reporters, “We do not belong to any organisation. We are students and we are unemployed. Our parents work as labourers, and farmers, and some are small shopkeepers. An attempt is being made to suppress our voices.”

Serious questions are already being questioned about the security breach, which comes on the 22nd anniversary of the terror attack on the old Parliament building. In fact, hours earlier, Prime Minister Narendra Modi and President Droupadi Murmu led a tribute to the nine people who were killed.

Following the security breach yesterday, the area around Parliament was turned into a fortress with the deployment of police and paramilitary personnel, while the Delhi Police’s Special Cell has been tasked with the investigation.
