NEW DELHI: All six people arrested in connection with Parliament security breach case were confronted with one another for a corroboration of the sequence of the incident by the Special Cell on Wednesday, police sources said.

All six have been kept at five different units of the Delhi Police Special cell, where they have been interrogated by security agencies several times.

On Wednesday, they were taken to the Counter Intelligence (CI) office of Special Cell and confronted with one another, sources said.

Two of them - Neelam and Manoranjan were already kept at CI office in New Friends Colony, while four others were brought from different ranges, sources said.

The seven days of police custody of four accused - Sagar Sharma, Manoranjan D, Neelam, and Amol Shide is ending on Thursday.

An officer privy to the probe said the investigators may seek further custody of all four for a few more days as there were still several angles left to be scrutinised.

The data of the mobile phones, which were stated to be destroyed, by two other accused, Lalit Jha and Mahesh Kumawat, are yet to be accessed.

The investigators are supposed to visit various locations along with the accused, which is yet to be done, the officer said.

In a major security breach on the anniversary of the 2001 Parliament terror attack, two persons -- Sagar Sharma and Manoranjan D -- jumped into the Lok Sabha chamber from the public gallery during Zero Hour, released yellow gas from canisters and shouted slogans before being overpowered by the MPs.

Around the same time, two other -- Amol Shinde and Neelam Devi -- sprayed coloured gas from canisters while shouting "tanashahi nahi chalegi" outside Parliament premises.

Lalit Jha and Mahesh Kumawat walked into a police station on their own as the probe heat became intense.
