Pappu Yadav, RJD MP expelled from Bihar, allegedly behaved roughly with an airhostess of a Jet Airways flight Patna today after she asked the legislators not to throw food scraps down the aisle . The incident occurred when the Patna plane was on its way to New Delhi, airline sources said. "Yadav was extremely undisciplined with cabin crew when she asked him not to throw food scraps in the driveway and also misbehaved with her," said a source from the airline. When contacted, Yadav denied having engaged in any fight on the flight. "Nothing like that happened," said Yadav. Even Jet Airways reacted very cautiously and will not disclose the identity of the passenger while admitting an incident on board the Patna flight. "The captain of the flight 9W-728 before landing at Delhi ATC asked for security assistance at the door for disruptive aboard guest. The guest was conducted by the arrival in security agencies "Jet Airways said in a statement. An official also said that CISF no complaints were received in this respect. "Nobody either the airline or its staff filed a complaint with us about the incident," the official said.
