HOUSTON -

A small northeast Houston grocery store had to shutdown after an early morning fire Tuesday.

Houston firefighters were called to the Queen Saver Supermarket on Huffman and Cavalcade around 4:30 a.m.

It took crews about 15 minutes to get the flames under control.

Upon closer inspection, there were signs the fire may have started from an outside electrical box.

Investigators believe it spread up an outside wall and into the attic.

The store was so badly damaged, it was closed for repairs.

Firefighters said it could take days to get the store repaired and ready for an inspection.

The store was closed when the fire started, so no one was injured.
