The NSW Bomb Squad was rushed to Cooma from Sydney last week to dispose of a large quantity of explosives that had been mysteriously located.
Parts of the town were rocked by the sound of the explosives being detonated after the material was taken to Cooma tip to be safely destroyed.
However, mystery surrounds the exact nature of the explosives, how they were discovered, and who owned them.
It is also not known at this stage whether any charges will be laid over the discovery and storage of the explosives.
Yesterday (Monday) neither Cooma nor Queanbeyan police were able to provide vital details of the explosives, and what risk if any they posed to the Cooma community.
Police did not provide information about the exact location of the explosives nor how they received information about the whereabouts of the material.
Police did, however, confirm that there was a 'substantial' amount of explosives.
It has also been confirmed that NSW Fire and Rescue and Cooma paramedics were called in at lunchtime last Wednesday as the explosives were transported to the Cooma tip by the Bomb Squad.
The emergency services personnel were on standby until about 6.30pm.
Rolling road closures were in place as the explosives were transported. Loud explosions were heard as the material was detonated.
