Hamilton's central police station on King William St. was closed off for a short time Thursday morning after a concerned citizen showed up with a grenade they had found.

The individual told police they had found the grenade in a home after the homeowner had passed away, saying they didn't know how to safely dispose of it.

Authorities secured the area to ensure no officers or members of the public were at risk.

The grenade, wrapped in duct tape, was removed from the trunk of a car before being disposed of.

Police are reminding the public it's never a good idea to handle explosives of any kind.
