Heavy security arrangements were put in place across the national capital on Saturday as the Cockroach Janta Party holds its second protest at Jantar Mantar, with police deploying extensive surveillance and crowd-control measures, officials said.

The protest began with heightened police presence, with supporters arriving from different parts of Delhi and neighbouring States.

Authorities have granted permission for the demonstration, officials said.

CCTV cameras were installed in and around the protest venue to monitor the gathering in real time, while around 270 body-worn cameras will be used by police personnel deployed at the site to ensure transparency and document proceedings, according to officials.
