A Hong Kong-bound Dragonair jet with 256 people on board was forced to make an emergency landing in southern Japan on a flight from Tokyo, after a drunken passenger allegedly assaulted a stewardess. Fellow passengers overpowered the 40-year-old Turkish man after he argued with another passenger and then allegedly pushed a flight attendant to the ground around two hours after the flight took off from Tokyo's Narita airport on Monday afternoon. The captain diverted the plane to Fukuoka in southern Japan where passengers and cabin crew escorted the man off the Airbus A330 to waiting police, who arrested him for assault. No one was seriously hurt in the incident, which resulted in a 28-hour delay for passengers on Flight KA361. It had left Tokyo at 3.45pm on Monday for the five-hour flight to Hong Kong but touched down in Fukuoka at 6.16pm. The 244 passengers on board, including three infants, and 12 crew were put up overnight in a hotel after police asked them to help with witness statements and inquiries. Passengers quoted in Japanese news reports yesterday said the suspect had been drinking beer in the airport before boarding and drank four glasses of whisky and cola in the early stages of the flight. A spokeswoman for Dragonair was unable to confirm how many drinks the man had been served in the course of the flight but said he had 'not appeared intoxicated' to cabin crew. She confirmed that the incident had taken place in economy class. The spokeswoman said the decision to divert the plane was taken after the passenger 'became aggressive and abusive and was deemed to be a potential danger to those on board'. 'As a result, the passenger had to be restrained, and established procedures to ensure the security of the cabin were enacted by the cockpit crew and cabin crew as a precaution,' she said. Andy Tung, chief operating officer of Dragonair, said: 'We understand the police in Japan are continuing their investigations. 'While not all the details of the incident are known at this time, I would like to commend our colleagues and passengers for their actions and understanding.'
