* Some speculate that he could be Chinese intelligence official or a hacker

A mysterious Chinese blogger has provoked a storm of speculation online over claims he predicted the disappearance of an AirAsia flight thirteen days before one vanished.

In a series of posts which have gone viral, the man appears to warn that the airline would be targeted by a shadowy group he calls the 'Black Hand' which he claims brought down Malaysian Airlines flights MH17 and MH370 earlier this year.

An AirAsia flight went missing yesterday with 162 people on board after losing contact en route from Surabaya in Indonesia to Singapore in the third crisis for a Malaysian carrier this year.

Since its disappearance, social media users have reacted with astonishment at the apparent prediction, while others claim the posts were probably just edited afterwards to make it look authentic.
