In light of the recent incident on board 6E 5317 from Mumbai to Lucknow, we wish to inform that we are suspending Mr Kunal Kamra from flying with IndiGo for a period of six months, as his conduct onboard was unacceptable behaviour," the IndiGo airline said in a tweet while tagging Civil Aviation minister Hardeep Singh Puri.

"Hereby, we wish to advise our passengers to refrain from indulging in personal slander whilst onboard, as this can potentially compromise the safety of fellow passengers," it said.

Replying to IndiGo's tweet, Puri also condemned Kamra's behaviour and advised other airlines to impose similar restrictions on the stand-up comedian. He said,"offensive behaviour designed to provoke and create disturbance inside an aircraft is absolutely unacceptable and endangers safety of air travellers".

Kamra allegedly heckled Goswami, the editor of Republic TV, on IndiGo's Mumbai-Lucknow (6E5317) flight on Tuesday.

His act, however, gained support from many Twitterati, including Congress MP Shashi Tharoor who, referring to Goswami, said that "it was time someone gave him a taste of his own medicine.

While Goswami can be seen sitting in the plane and watching something on his laptop with his earphones plugged in, Kamra is heard telling him, "Viewers want to know if Arnab today is a coward or a nationalist. Arnab, this is for national interest. I am part of the tukde-tukde narrative. You should deflate me. You should take the enemy of the states down. You should make sure that the country is in safe hands of Narendra Modi."

"You should fight against dynasts like Rahul Gandhi, who I support, on 10 Tughlaq Lane. Arnab, you should have a reply, Arnab. Arnab, are you a coward or are you a journalist? Are you a coward or are you a journalist or a nationalist? Who are you, Arnab? Who are you?" he can be heard saying in the video clip.

Later, Kamra in a statement explaining what happened onboard the IndiGo flight and said that he had apologised to all crew members, pilots, but expressed no remorse for what he said to Goswami. "I apologise to all passengers except one.
