Extending his support to the protests by youths demanding justice for the Delhi gangrape victim, anti-corruption crusader Anna Hazare on Sunday called for stringent laws and fast-track trials in such cases.

"Youths gathered on the streets to demonstrate are passionate patriots. Their anger and the non-violent ways of demonstration shows that they have full faith in the country's democratic system and the Constitution," Hazare told PTI at Ralegan Siddhi, his native place in the district on Sunday morning.

"The incident of gangrape in the national capital shows that criminal and anti-social elements are not afraid of the government machinery," he said.

"Therefore, government has to change the laws to give severe punishment to those who indulge in crime against women. Fast-track trials are needed against such crimes in the country," Hazare said.
