Irked by 'pink chaddi' campaign against him following his threat to disrupt Valentine's Day celebrations, Sri Ram Sene leader Pramod Muthalik has said he would soon sue the rights activists behind it.

Right wing Hindu group Sri Rama Sene founder Pramod Muthalik and over 100 others were detained by Karnataka police on Friday to prevent them from creating any trouble on the Valentine's Day Saturday, police said.

After triggering a war of words and a cheeky campaign by bloggers by his threat to marry off young men and women publicly displaying affection on Valentine's Day, Pramod Muthalik, founder of a rightwing Hindu group, now says his moral brigade won't be prowling on the streets on February 14.
