For a recent example of volatility in China itself, just look at Baidu, which suffered a nose-bleeding 42% plunge its shares during one stretch last year on worries about new competition.
Mr Betondi claimed his nose and face started bleeding and at one point he thought he was going to suffocate as staff allegedly forced him under a seat on the aircraft.
Calls tweeted included a woman who was bleeding from the nose after an assault in the street in Littlehampton and a report about a brother and sister assaulting each other in St Leonards.
