He joined the probe around 12 PM today and was questioned in two rounds by two police teams, a source said.
Ashutosh was questioned along with Khalid and Anirban, also charged with sedition at the same police station yesterday. Most of the queries revolved around their role as organisers of the February 9 event on the varsity's campus during which anti-national slogans were allegedly raised.
Ashutosh, a former JNUSU president, was one of the six students wanted by the police after the arrest of student leader Kanhaiya Kumar.
