Firefighters from Mount Airy assisted companies in neighboring counties at house fires Sunday and Monday.
The blaze early Sunday morning at an unoccupied home was ruled an arson yesterday by the state fire marshal.
The home in the 700 block of West Watersville Road, which sustained $5,000 in damage, is in Howard County just east of Mount Airy. Neighbors reported the house engulfed in flames, and 25 firefighters from Mount Airy and Lisbon of Howard County responded.
The blaze was extinguished quickly, according to the fire marshal's office, although units remained at the scene for about two hours.
The fire began about 3:15 a.m. on the outside of the two-story, wood-frame home, prompting fire investigators to suspect arson, the fire marshal's office said. No one had been arrested yesterday, and investigators were continuing their inquiry.
Mount Airy and Union Bridge also assisted Frederick County early yesterday at a house fire on Westvale Court, north of Mount Airy.
Units remained at that scene for more than three hours, and Winfield transferred an engine to fill in at the Mount Airy station.
