Scottish helicopter accident: Rescuers battle to free revellers trapped inside The Clutha pub after chopper crash

Scottish emergency services are scrambling to rescue people trapped in the wreckage of a Glasgow pub after a police helicopter crashed into the building, killing at least one and injuring dozens.

The chopper smashed through the roof of The Clutha pub, where more than 100 revellers had crowded in to see a band play on Friday night ahead of St. Andrew's Day, which celebrates Scotland's patron saint.
Police said 32 people had been taken to hospitals across Scotland's biggest city after the helicopter plunged into the riverside bar at 10:25pm (local time).
Emergency services worked through the night in a bid to recover people from the scene.
Witnesses said the helicopter, with two police officers and a civilian pilot on board, dropped like a stone, while people inside the pub heard a whoosh before the roof caved in and the air filled with dust and screams.
Firefighters said they had made "some contact" with an unknown number of people in the wreckage of the one-storey building, which was "very unstable".
"It's a case of working hard within the building to try and determine how many casualties are there," fire brigade officer Lewis Ramsay told reporters.
"We are determined that we are going to get the building stable and we will be in there to carry out those rescued."
Mr Ramsay said the 125 firefighters at the scene had "rescued numerous casualties" who had "multiple types of injuries".
Scottish first minister Alex Salmond - who just days earlier was celebrating the release of a legal blueprint for independence - called it a "black day" for Scotland as he sent his condolences to the bereaved.
Police Scotland chief constable Stephen House said 32 people had been taken by ambulance to three Glasgow hospitals following the crash on Friday night.
"Sadly I can also confirm one fatality. We expect that number to increase over the coming hours," he told reporters.
Asked if there were people still alive trapped in The Clutha bar, where more than 100 people were watching a band play, constable House replied: "We can't say that definitively at this moment in time".
Scotland's police chief was speaking alongside Mr Salmond outside the command centre in Glasgow which is co-ordinating the multi-agency emergency response.
"Our condolences go to those who will be bereaved; our solidarity with those who've been injured," Mr Salmond said.
"All of us have seen over the last few hours the speed and the effectiveness of the mobilisation of emergency services in dealing with this tragedy.
"We've also heard of the instinctive courage of ordinary Glaswegians going to assist their fellow citizens in extremity.
"This is a black day for Glasgow and for Scotland. But it's also St. Andrew's Day and it's a day we can take pride and courage in how we respond to adversity and tragedy.
"And that response, from our emergency services and from ordinary citizens, has been exemplary.
"It's a day we can take great pride on how we've responded to this extraordinary tragedy."
Police officer Rose Fitzgerald said it was too early to say why the Eurocopter EC135 T2 helicopter crashed.
"A full investigation is now underway however at this early stage it is too early to provide details on why the helicopter came down," she said.
"We are working hard to recover people still inside the building."
The Air Accidents Investigation Branch has sent a team to the scene.
