LINCOLN, Neb. (AP) — Fire officials say a fire that destroyed a longtime grocery store near downtown Lincoln has been ruled an accident.

Firetrucks were dispatched a little before 2:15 a.m. Thursday to Ideal Grocery on South 27th Street. Investigators say flames reached upward of 30 feet and some were still visible 2½ hours after the first alarm.

After getting the fire under control, firefighters remained on the scene for several additional hours to pour water on hot spots.

Officials say they believe the fire started in the store’s compressor room where Freon was pumped into coolers.

A portion of the store’s roof collapsed but no injuries were reported.

The store opened in 1920. Battalion Chief Jeremy Gegg told the Lincoln Journal Star that the building is a total loss.
