There was a major security breach during Zero Hour in Parliament at 1.02 pm on Wednesday after two men, both carrying smoke canisters emitting an as yet unidentified yellow smoke, jumped from the visitors' gallery and ran into the Lok Sabha chamber. Incredible footage from the House's CCTV system showed one man, wearing a dark blue shirt, leaping across desks to evade capture, while the second was in the visitors' gallery spraying smoke. Both men were overpowered by MPs and security staff. Lok Sabha resumed at 2 pm, with Speaker Om Birla making a brief statement. "We are investigating the matter and have asked Delhi Police to join the inquiry," he told understandably agitated MPs.
