Smoke pours from roof of Sydney prison as inmates climb up

Prisoners at Parklea Correctional Centre in Sydney have climbed onto the roofs of buildings at the prison this afternoon.

Aerial shots showed a number of prisoners standing and walking on the roofs of the facility.

Smoke was also seen pouring out of the roof.

"The Security Operations Group and correctional officers are currently responding to an incident at Parklea Correctional Centre after 14 inmates climbed onto the roof of an accommodation wing about 2pm," spokesperson from MTC-Broadspectrum said.

"Parklea's Immediate Response Team officers and the Security Operation Group are managing the situation to safely bring the inmates down from the roof."

Police have since gained access to the roof and have been seen standing over inmates who are lying down.

Police and fire units are on the scene.

The prison is located in Sydney's far north-west, near Quakers Hill.
