Police and prison staff are refusing to elaborate on their investigations into the jailbreak as more details emerge about the activities of the two inmates while they were on the run.

Two men dressed in prison greens held-up a Domino’s pizza outlet in Kelso early last Saturday before apparently returning to the prison.

During the hold-up, Domino’s staff were forced to the ground as the men – one armed with a knife and the other with what staff believed could be a rifle – raided the cash register before fleeing with a small amount of money.

A white Toyota Hilux 4WD that had been reported stolen from Porters Retreat on January 17 was found near Shooters Hill on Saturday afternoon, just hours after it had been used in the armed hold-up at Domino’s.

But another Porters Retreat property owner reported a break and enter at a vacant farmhouse on his land some time on Tuesday or Wednesday, raising fears the inmates may have broken out – and back in to the jail – on more than one occasion.

After being away for a couple of days, the Porters Retreat farmer found thieves had tried to steal his ute but had driven it into a service pit. But the farmer said that when he entered the vacant farm house it appeared someone had been camping there for some time.

A number of doors had been ripped off cupboards and blankets had been removed.

The farmer said he contacted the Shooters Hill Correctional Centre to inform them that something strange was going on and was told by staff that all prisoners had been accounted for.

More details about the stolen ute that was used in the Domino’s hold-up have also emerged.

A timber harvester operator reported seeing the Hilux parked in thick scrub on Friday – before the hold-up – and then on Saturday afternoon he noticed the vehicle had been moved and was parked 500 metres from the boundary fence of the prison. After finding some paper work in the ute, the harvester operator contacted the ute’s rightful owner, who went to claim it.

The owner then contacted prison staff to say he had found his ute and asked them to contact police as a home-made gun, knife and clothing had been left in it.

Calls to police and prisons staff have shed no light on the breakout and break-ins, as they refuse to comment while police continue their investigations.
