The Office of the State Fire Marshal Bomb Squad determined the devices on the yard signs, located on Maryland’s Eastern Shore Sunday and Monday, weren’t harmful and were removed.
The devices were found to be alarms that rang if removed from the political signs.
The signs were stationed on public land, which is not allowed under state law.
