The discovery on an explosive ordnance closed the Hilo Transfer Station for a short period on Thursday.
Hawai`i Police Department officials say that the ordnance was found just after 2 p.m. and upon the discovery the site was evacuated for about 40 minutes while the device was examined. The explosive device was found to be a non-functioning grenade, with no detonation ability.
The Transfer Station was reopened at about 2:45 p.m. following the area being determined as safe.
Police say it is not clear how the device ended up at the dump site. The device was found on the roadway in front of one of the dumpsters at the site.
HPD reminds the public to treat the discovery of these devices as live and take precautionary measures to ensure their safety and the safety of others and to report these findings immediately to authorities by calling 9-1-1.
