Three people have been killed after a police helicopter crashed in the Scottish city of Glasgow, the BBC reported on Saturday, according to dpa. Scotland Police said 32 people were evacuated to hospitals across Glasgow and rescuers were searching through the ruins of the building where the helicopter carrying two police officers and a civilian pilot crashed. Witnesses said there were about 120 people inside the building when the accident occurred at 10:25 pm (2225 GMT) Friday. "A full investigation is now under way however at this early stage it is too early to provide details on why the helicopter came down," said deputy chief constable Rose Fitzpatrick. "We are working hard to recover people still inside the building and we will make further details available when we have them," she added.
