New Delhi, Feb 12 (PTI): Talking tough, Home Minister Rajnath Singh today warned of "strongest possible" action against those involved in raising anti-India slogans at an event in JNU campus here, saying such activities will not be tolerated.

"If anyone raises anti-India slogans, tries to raise questions on country's unity and integrity, they will not be spared. Stringent action will be taken against them," he told reporters here.

The Home Minister said he asked the Delhi Police to take "strongest possible action" against those who were allegedly involved in anti-India acts in Jawaharlal Nehru University campus recently.

A group of students on Tuesday held an event on the JNU campus and allegedly shouted slogans against the government and the country over the hanging of Parliament attack convict Afzal Guru in 2013.

The event occurred despite varsity administration having cancelled the permission following a complaint by ABVP members, who termed the activity as "anti-national".

Delhi Police yesterday registered a case of sedition in connection with the event following complaints by BJP MP Maheish Girri and ABVP
