CCTV chiefs gagged over hurdler Liu Xiang's injury at London Olympics
State broadcaster knew that top athlete was unfit before he crashed out at first hurdle

State television bosses on the mainland knew sporting icon Liu Xiang was seriously injured at the London Olympics, but were prevented from saying so by a government gagging order.
Millions of fans were stunned when Liu crashed to the track in agony after hitting the first barrier in his 110 metres hurdles heat.
It was later revealed he had a torn right Achilles tendon - the same injury that forced him to withdraw from the Beijing Olympics four years earlier.
But it has now emerged that representatives of China Central Television (CCTV) knew that Liu was injured when he arrived in London. And they were stopped from revealing the truth by the propaganda authorities.
A senior editor of CCTV's Olympics broadcasting team told the South China Morning Post yesterday that the gagging order was issued the day after Liu arrived in London on August 3.
It was believed Liu had over-exerted himself while training in Germany and that his team knew he was injured.
