A guard then checked on Mr Lightbody and found him totally unresponsive despite shaking him and shouting at him.
Both guards did nothing else initially. They sat at their base for 20 minutes, with one continuing to file while the other made himself a hot drink and ate a sandwich.
During this time, the prison wing's manager and supervisor left the unit. The supervisor told the guards that he was off for the next week and that it was up to them to "sort it out", the report said.
The supervisor denied being told of the assault.
Nurses were finally called, but the first arrived without an emergency first aid kit.
An ambulance was eventually called at 5.02pm, more than 2 hours 30 minutes after the attack, arriving 11 minutes later.
The victim ended up with brain damage and is suing Corrections for failing to exercise a proper duty of care. I think they've got a good case. But the report is also clear in blaming Serco's understaffing for the incident, and I'd hope that they're required to pay any eventual damages.
Meanwhile, its also a warning against the dangers or prison privatisation. Privatised prisons are inherently understaffed - its how they make their profits - and combined with prisons' inherent culture of neglect towards prisoners, its basicly a recipe for this sort of failure.
