FORT WAYNE, Ind. — Firefighters responded to a fire at the OmniSource building just southwest of downtown Fort Wayne Friday afternoon.

Smoke could be seen coming from the building at 2511 Taylor St. around 4 p.m. A ladder truck was at the scene, and at least one firefighter was on the roof of the large structure.

A Deputy Chief told WANE 15 the exact cause has not been determined but investigators suspect the fire was tied to machinery.

The fire was contained to machinery located in the middle of the building, a report from the fire department said.

20 employees were reportedly on the property and self-evacuated. No one was hurt.

Crews said it took about an hour to get the fire under control due to the large size of the structure.

Police and firefighters blocked off the street to traffic but roadways were opened back up around 4:30 p.m.
