State and federal officials say a fire at a Missouri probation and parole office was deliberately set.

A reward of up to $5,000 is being offered for information about the fire that damaged the Missouri Board of Probation and Parole office in Nevada last week.

The fire early Wednesday caused heavy fire damage to the west end of the state office, and heat and smoke damage throughout the building.

Nevada fire Chief Bill Thornton says the state fire marshal and the Bureau of Alcohol, Tobacco, Firearms and Explosives both determined the fire was arson.
