GRAND ISLAND, Neb. (AP) — A portion of a downtown Grand Island building has collapsed during a fire.

Authorities say one firefighter suffered minor injuries fighting the blaze, which was reported about 8 p.m. Sunday and extinguished about four hours later. Some firefighters remained on the scene to combat hot spots. The building housed Ron’s Transmissions and other businesses.

Fire Chief Cory Schmidt says fire crews and trucks from the Grand Island Rural Fire Department and from Hastings and St. Paul helped his firefighters.

The fire cause is being investigated.
