An imprisoned gang member organised a bar tab for Corrections guards drinking at a pub after hours in an attempt to corrupt them.
But Corrections said the prison guards didn't take the bait and alerted managers.
Corrections then called in its Intelligence and Integrity Support Team.
The Intelligence unit tapped prison phone calls and it was discovered that the bar tab, which was left anonymously for the guards, had been orchestrated by a prison inmate.
