Officials say it could be a week before investigators know what caused the fire that ripped through the Calvert City Hall.
Investigators have already ruled Friday's fire an arson and they say the reason it was set was to cover a break-in. Authorities still don't know what, if anything, was stolen.
The Bureau of Alcohol, Tobacco and Firearms (ATF) and the State Fire Marshal's Office are working the case.
Part of the building was severely damaged and employees have been advised not to go inside.
The Calvert Police Department says it has re-located to a building at 613 Main Street in Calvert and other departments are expected to move there as well.
The police department urges residents who have an emergency to call the Robertson County Sheriff's Office at 828-3299.
