JOHN McGarrigle was on the bus to collect his girlfriend from hospital when a fellow passenger broke the news to him that a helicopter had smashed through the roof of the Clutha Vaults pub.

"I knew right away," he said. "I didn't believe it but as soon as the guy showed me a picture of it on his phone I said 'that's it, my dad's dead'. I knew he was there - he's there every Friday - and I could tell from where the helicopter had fallen that he would have been sitting right underneath. It was his favourite seat - he sat in the same place every week."

McGarrigle - looking exhausted after a night in the cold - said he would have been sitting beside his 59-year-old father, also called John, if his girlfriend had not become ill with a sudden asthma attack earlier on in the day. Instead, he was on his way to pick her up, and was planning to drop in at the pub on his way home with her to say hello to his father and the friends who gathered around their favourite table every Friday night.

By the time he reached the scene, McGarrigle had to be pulled back by police as he rushed through the cordon trying to reach the pub where he believed his father was trapped beneath the rubble where the roof had caved in.

"I've been here all night. My wee sister brought me a warm jacket at 2am - until then I'd just been wearing my tracksuit. I've tried phoning my dad on his mobile but there's no answer and he hasn't been home all night.

"His best friend, Sammy, is missing as well. His wife and daughter have been down here looking for him. I didn't know what to say. I feel sure that my dad's dead but you don't want to say that to someone else. One of their other friends, a woman who was with them, managed to get out.

''She went to the toilet a couple of minutes before and that's what saved her, because she was in a bit of the building that's solid concrete and it didn't take so much of the impact.

"She said she just heard this loud bang and when she came out everything was just dust and rubble. She managed to make it out the exit and she's okay."
