BILLINGS, Mont. (AP) - A fire at the Western Sugar factory in Billings caused about $35,000 in damage.

Firefighters were called to Western Sugar at about 10 p.m. Sunday after workers found a fire inside one of the factory's pulp dryers.

Fire Marshal Bill Tatum says machinery sustained moderate damage from fire and smoke.

A Western Sugar employee was taken to Billings Clinic for treatment of minor smoke inhalation. His condition was unknown.

Tatum says the cause of the fire remains under investigation.
