Two Waikato prison officers were taken to hospital with head injuries after two inmates allegedly assaulted them while trying to escape last night.
One officer remained in hospital for observation and the other had been discharged, Corrections Department chief executive Ray Smith said today.
The inmates escaped from their cells at Waikeria Prison, south of Te Awamutu, about 8.30pm. They assaulted the male officer who then secured himself in the guard room.
The female officer had retreated to call for help, when the prisoners found her and assaulted her, he said.
She talked to the prisoners while waiting for other staff to arrive.
