The POA are aware of the attack on two prison officers at HMP Full Sutton.
Until the full facts of the incident are known, we do not wish to speculate or indeed compromise an ongoing police investigation.
We can confirm that officers sustained injuries and, had it not been for the professionalism of prison officers dealing with this violent incident, the outcome could have been worse.
