Houston firefighters battled a massive blaze inside a northeast Houston art store Wednesday morning.

The fire broke out around 2:45 a.m. at the Art & Apparel Shop at 2121 North Main Street near Gargan Street.

Firefighters said most of the building was burned and the fire did significant damage to the inside of the store.

The owners told Local 2 they believe the fire was intentionally set, but fire investigators have not yet made that determination. The store was closed at the time.

No one was hurt.

The cause is under investigation.
