Federal authorities are assisting an investigation into a suspected arson attack after an Israeli flag was apparently set on fire outside a historic building in Zionsville, causing more than $150,000 in damage.

Firefighters were called to 195 South Main Street at about 1:41 a.m. on Friday, July 10. The house, which once served as an antique shop in Zionsville’s historic commercial district, was empty at the time.

Crews brought the blaze under control within approximately 15 minutes, and no injuries were reported.
