Four prison officers have been hospitalised, one with a suspected broken nose, after a vicious attack by an inmate at Cloverhill Prison.
The incident happened at 3.30pm yesterday when the inmate, a foreign national, was being escorted through the reception area.
He became violent, and the four officers were trying to restrain him when they sustained their injuries.
"The prisoner went berserk and lashed out. It was a very violent and unexpected outburst," a source told the Herald.

"The inmate will be dealt with under standard prison procedures."
