Twelve prison inmates are being kept in quarantine after testing positive for Coronavirus, The Correctional Services agency said.

The patients are all being kept in isolation in Division 6 at the Kordin prison.

The division is being used as a quarantine facility to isolate incoming prisoners, the agency said..

"This is a precaution against the spread of COVID-19 - prisoners are held in quarantine and all necessary tests are performed during that period. In fact, all the positive cases were related to people who had recently entered the facility," their statement said.

Another eight inmates who had tested positive cases over the last few weeks have recovered and have been removed from the division.
