Students 'packed like sardines' on balcony before tragic collapse

Irish students were “packed like sardines” on a balcony which collapsed in California, killing six of them and injuring seven others at a 21st-birthday party, an expert has said.

Engineering crews have been inspecting jagged broken beams of wood sticking from the building in Berkeley, marking where the balcony had snapped off. Pieces of wood came away, falling to the ground, as the engineers touched them.
