An inquest has been shown CCTV footage of the moment an armed robber burst into a betting shop in Plymouth. A group of customers disarmed Alan Levers and held him on the floor as others raised the alarm.
By the time police arrived he was unconscious. He was later pronounced dead. At his inquest today, the Coroner said he died from a combination of factors - one of which was that he was wearing a gas mask which had the respirator pressed against the floor.
