The RNC was called to Commonwealth Avenue in Mount Pearl Saturday morning after someone found explosives detonators on the street.
The items were safely recovered without incident by the RNC explosive disposal unit and the K9 unit.
However, police have also said that these items are not part of the lot that was stolen from City Sand and Gravel in Paradise late last month.
About 25 pounds of dynamite, detonators and other explosives equipment that were stolen from that business have yet to be recovered.
It is unclear where the material recovered today came from.
The RNC have also said it is concerned the public might find more of these detonators. It is warning people that these devices can be dangerous, and anyone who finds one to should avoid handling it and call police at 729-8000 immediately.
The RNC is continuing its investigation into both incidents.
