New Delhi/IBNS: Trinamool Congress MP Derek O'Brien was on Thursday suspended from Parliament's upper house Rajya Sabha for the rest of the winter session for the "breach of privilege".

A war of words occurred between Rajya Sabha Chairman Jagdeep Dhankhar and Derek after the latter demanded a discussion on the breach of security which occurred inside Parliament on Wednesday.

As Derek demanded a discussion leading to a chaos in the House, Dhankhar said, "I hereby name Derek O'Brien to leave this House immediately. What are you doing? Mr. Derek O'Brien, you have committed a breach of privilege.

"Leave this House immediately. The House is not in order."

"Shameful incident," added the Chairman.

Derek was joined by other opposition MPs, who demanded the presence of Union Home Minister Amit Shah to answer for the incident, where two men jumped from the visitors' gallery into Lok Sabha and burst yellow smoke canisters leading to panic in the lower house of Parliament.

The four, who were arrested over the security breach in Parliament, have been charged under the anti-terror law and Unlawful Activities (Prevention) Act or UAPA.

The four will be produced in the court on Thursday.

The Union Home Ministry has formed a panel to probe into the shocking Parliament security breach that happened on Wednesday when the proceedings of the Lok Sabha were on.

The incident coincided with the 22nd anniversary of the terrorist attack on Parliament.

Six people were involved in the planning and execution of a major security breach in Parliament on Wednesday, media reports said.

Two individuals named Sagar Sharma and D Manoranjan deployed yellow smoke canisters inside the Lok Sabha, and two others - Neelam Devi and Amol Shinde - burst red and yellow canisters outside the Parliament. The fifth has been named as Lalit Jha, at whose Gurgaon home the other five stayed.

The sixth is Vicky Sharma, also from Gurgaon, and he has also been arrested.

Sagar Sharma and Manoranjan, who were seated in the Lok Sabha's visitors' gallery before launching this shocking disruption, were given entrance passes requested by BJP MP Pratap Sinha's office.

The incident happened when Zero Hour of the House was in progress.
