A female medical student was crushed to death under the weight of snow when a timber roof caved in at an underground garage party in Siberia.
Tuyana Prushenova, 22, died when the thickly-packed snow caused the makeshift roofing to collapse at the disused cafe in the scientific research city of Akademgorodok, Novosibirsk.
Four of the 200 revellers were injured including a man who suffered a broken pelvis and a woman who fractured her ankle at the 4am rave with two others suffering from frostbite.
