After cordoning off the area, police found the bag to contain 1.2 kg of explosives and the detonators needed to set it off. Some of the detonators were found to be too damaged to be safely moved. After the bulk of the find was removed by police, the damaged detonators were destroyed in a controlled explosion at the site.
So far, police do not know the origin of the explosives, nor how they came to be where they were found and have asked members of the public any information they may have.
