"Yet again, this time inside the aircraft, a man tries to strangulate me," Kanhaiya Kumar tweeted.
Kumar alleged that the airline staff refused to take any action against the attacker.
"After the incident, Jet Airways staff completely refuses to take any action against the man who assaulted me. Basically Jet Airways sees no difference between someone who assaults and the person who is assaulted. They will deplane you, if you complain," he added.
Kumar was arrested and on charges of sedition charges on February 12 after he allegedly raised anti-India slogans at the JNU campus. He was later released on bail.
