Two inmates hospitalised, tear gas used after Long Bay prison brawl

At least two inmates have been injured in a Sydney prison brawl that only ended after security officers used tear gas.

Corrective Services NSW said the brawl on Sunday broke out between five remand inmates in a yard at Long Bay Hospital, a maximum to minimum security facility in Matraville.

Staff needed to use tear gas to break up the fight.

NSW Ambulance said two inmates were taken to nearby hospitals with puncture wounds.

The condition of the other three inmates was unknown but none required hospital treatment.
