At the time of the disaster, many stadiums had perimeter fencing between the stands and the pitch to prevent incidents of football hooliganism – particularly pitch invasions – which were rife during the 1980s. The main stand at Bradford was not surrounded by fencing, and therefore most of the spectators in it could escape onto the pitch – if they had been penned in then the death toll would inevitably have been in the hundreds if not the thousands. However, the turnstiles were locked and none of the stadium staff were present to unlock them, leaving no escape through the normal entrances and exits. Most of the fans who took this escape route were killed or seriously injured. Fans in the next stand (the "Bradford End") pulled down the fence separating them from the pitch.
