Very sad indeed. Well the incident took place in Thailand, so the family should lodge a complaint with Thai police against Unilever, coz lodging a complaint here in Pakistan wouldn't do any good... but I guess Unilever would have been smart enough to have the contestants sign a waiver form.. dunno if that'll hold in a court of law.
But this is very tragic.
Why did they not have divers in the water with oxygen tanks?
