Over 20 protesters were detained by the Mumbai Police officials on Tuesday after they allegedly walked onto the safety net suspended in the state secretariat Mantralaya in south Mumbai during an agitation staged by people affected by a dam project, police said, reported the PTI.

The protesters shouting slogans and carrying placards walked onto the net suspended in the premises, even as police personnel, including officers, tried to drag them off, an official said, as per the PTI.
