My take it on is Sky pick up some strange readings on these tests and suspend the rider, Henao isn't happy at all, goes home to Columbia in a fit of pique while his agent leaks the story to the press. Sky issue a statement after being contacted by the Gazetta.
So it sounds like Sky didn't have to suspend him but choose to anyway, because of their own concern over his tests. Presumably they would have liked to have kept in house until the 'research' had occurred, but it isn't an official sanction. Henao storms back home, agent leaks the story....and the clinic turns on Sky. Quel surprise.
So maybe it is PR, or just maybe Sky suspended a core member of their squad because they were concerned over his figures despite the lack of any action from the governing body, or any official sanction.
But I forgot: Sky are the dark side of the force, and Brailsford the devil incarnate. Lets not bother even giving them the benefit of the doubt, shoot first and ask questions later.
