A fire Wednesday night caused significant damage to a couple of business offices in Merrillville. Fire Chief Ed Yerga told the Region News Team they received the call at 7pm and spent about two-and-a-half hours at the scene. Chief Yerga says the fire is under investigation and there were three or four different locations inside the building where it may have begun. He stated that no one was in the offices at the time of the fire, located in the eight-thousand block of Tyler Street, and of the three that were damaged, only two were being occupied. No injuries were reported.
