Lalit Jha, the alleged mastermind of the security breach in parliament that shocked the nation, has surrendered. Sources said he had gone to the police station on Kartavya Path (the boulevard renamed ‘Path of Duty’ in the heart of Delhi) and surrendered. He has been formally arrested and the New Delhi District Police has handed him over to the Special Cell.

The Kolkata-based teacher was arrested from Delhi after being on the run for nearly two days.

Sources said the man claimed that he had gone by bus to Rajasthan’s Nagaur via Neemrana — where he he was seen last — and stayed at a hotel with two friends. Later, when he realised that the police were looking for him, he came back. At the police station today, he was accompanied by one Mahesh, sources said.

Four persons were arrested for Wednesday afternoon’s security breach in which two men — Sagar and Manoranjan — smuggled in smoke bombs and let them during the Lok Sbaha proceedings.
