A potentially explosive object resulted in the shutdown of a portion of a south-end street on Friday.
Thunder Bay Police responded to a call at a Fredrica Street residence shortly after 9:30 p.m. where they discovered a smouldering object had been thrown through a window.
The OPP's explosive disposal unit was then called to the scene, where it was confirmed to be an explosive with the intent to start a fire.
There were at least five police cars with lights flashing as access to Fredrica between Edward and Ford streets was prohibited.
