HASTINGS, Mich. (WOOD) — Crews from multiple agencies battled a large building fire in Hastings early Wednesday.

The fire broke out around 3:30 a.m. at the old Hastings Manufacturing building near the intersection of Mill and Hanover streets.

It’s unknown what caused the blaze.

A lieutenant with the Freeport Fire Department told News 8 that there were no reports of injuries and authorities don’t believe anyone was inside the building when the fire sparked.

Authorities say the fire caused a power outage in the Hastings area. The Consumers Energy outage map showed that thousands of customers lost power. It was restored later Wednesday.

The power outages forced Hastings Area Schools, Barry Intermediate School District, Maple Valley Schools, Barry County Christian School and Lakewood Early Childhood Center to close Wednesday.

Drivers were advised to avoid the area and seek an alternative route.
