As investigations into Parliament security breach on December 13 continue, the Delhi Police has recovered fragments of broken and burnt mobile phones from Rajasthan’s Nagaur, an official said on Sunday. Police have added IPC sections related to the destruction of evidence to the FIR against the accused.

An officer privy to the investigations said a few pieces of mobile phones were recovered on Saturday on the instance of Lalit Jha, who was among six arrested by the police in connection to the case. A team from Delhi Police’s Special Cell took Jha to Rajasthan’s Nagaur on Saturday, where he stayed with the help of accused Mahesh Kumawat, officials said.

Sources said the Delhi Police has decided to add more IPC sections, including Section 201 (destruction of evidence/disappearance of evidence) in the FIR registered on December 13. Police have filed terrorism charges under the stringent UAPA against the accused. Police officials said Jha and Kumawat intentionally destroyed the mobile phones to hide technical evidence related to the case.

The Delhi Police have arrested six persons so far — Sagar Sharma, Manoranjan D, Amol Shinde, Neelam Devi, Lalit Jha, and Mahesh Kumawat for their alleged involvement in the Parliament security breach case. Two men, Sagar Sharma and Manoranjan D, had jumped into the Lok Sabha chamber from the public gallery during Zero Hour, released yellow smoke from canisters, and shouted slogans before being overpowered by the MPs.

Around the same time, two others, Amol Shinde and Neelam Devi, released colored smoke from canisters while shouting ‘tanashahi nahi chalegi’ outside the Parliament premises. Jha, who was present outside the gate, had recorded the act on his mobile phone. After uploading it on social media and sharing it with his friends, he went to Nagaur in Rajasthan. Kumawat and accused Kailash, who are cousins, allegedly arranged his stay there.

Later, Jha and Kumawat came to Delhi and surrendered to the police.
