Thiruvananthapuram, June 22 -- Leader of Opposition in Keralam Assembly and former Chief Minister Pinarayi Vijayan on Monday alleged that contaminated water was used by police in water cannons to disperse protestors marching to the Legislative Assembly against the PM SHRI scheme, raising concerns over serious public health risks.

Speaking in the Assembly, Vijayan said the joint protest march by the All India Students Federation of India (AISF) and the All India Youth Federation (AIYF) was met with police action using water cannons. He, however, questioned the quality of water used.

"The police dealt with the march by using water cannons. The water used by the police through the water cannons was contaminated water," Vijayan said.
