"Help me. They are going to kill me."
This was the chilling and desperate plea from prison officer-turned-hostage David "Bud" Flanagan after rioting inmates at Barlinnie jail swarmed B-Block and staged a rooftop protest in January 1987.
Flanagan was one of several officers being held at knifepoint at the notorious Glasgow prison where a band of around 20 convicts in makeshift balaclavas made from blackened pillow cases and armed with truncheons, shields, and other weaponry, had seized control.
