Vacant Downtown Tulsa Building Burns Thursday Evening

Fire investigators are trying to figure out what started a huge fire in Tulsa's historic Pearl District Thursday night.

Tulsa firefighters were called out to the fire on the south side of 6th Street between Quincy and Rockford in the city's historic Pearl District around 8:30 p.m. 

The building belongs to the Rule Company, a fastener company that owns three buildings on the same lot.   

The building that burned was just to the north of the one the company uses for its warehouse and store front.  

The company says it had long-term plans for the building but it was mostly empty at the time of the fire.  

The owner's father saw the story about the fire on News On 6 and called his son to alert him to the fire.

The building was destroyed, the other two were not damaged.  No one was injured.
