A man and a woman were detained on Wednesday for protesting outside the Parliament building carrying cans that emitted yellow and red smoke. They have been identified as Neelam, 42, of Haryana's Hisar, and Amol Shinde, 25, of Maharasthra's Latur area.
The incident happened minutes after two people jumped into the Lok Sabha chamber from the public gallery and opened canisters that emitted a similar-coloured smoke, triggering panic among the MPs. Delhi Police Commissioner Sanjay Arora visited the Parliament to take stock of the situation after the twin security breach.
The area around the Parliament was turned into a fortress following the incidents with the deployment of police and paramilitary. The Delhi Police's Special Cell has been tasked with the investigation of both the incidents, according to officials. Forensic teams visited the Parliament to gather scientific and physical evidence.
