The punishment is almost medieval in its cruelty. Victims are forced to crouch down and hold their ears with their arms threaded under their legs. Beatings are often administered at the same time.
This brutal practice has its own name: the Hen, so called because those forced into the excruciatingly painful squatting position are said to resemble a chicken.
It is the kind of shockingly degrading treatment you might expect to feature in an expose of torture techniques, like say, the use of waterboarding (simulated drowning) on terrorism suspects. You'd be wrong, though.
