"Here is the state where women are the most unsafe as predators are everywhere who enjoy the patronage of the people in power," Punjab Congress chief Partap Singh Bajwa alleged.
"This is high time Badal should retire," he said.
Two minor sisters, aged 13 and 15 years respectively, were allegedly harassed by the conductor of a private bus owned by an Akali leader in Muktsar district on May 13.
"Coming close on the heels of molestation and death of teenage girl who was pushed down from a moving bus, here is yet another shocking case of two young Dalit sisters having been harassed by the conductor of a transport company owned by an Akali Dal leader," Bajwa said.
The former MP warned that Congress would organise strong protests to force the ouster of this government.
