OKLAHOMA CITY– Fire investigators are trying to figure out how a boat located inside a building caught fire inside a piping company Monday evening.

Firefighters rushed to J&B Pipe Supply, near S.E. 15th St. and Grand Blvd., after receiving word of a fire inside the building just after 6:30 p.m. Monday.

After forcing their way into the building, crews discovered that flames had engulfed a boat inside the warehouse.

Authorities shut down part of Grand Blvd. briefly while the blaze was extinguished.

The business was closed for the day when the fire started.

Fortunately, there were no injuries reported at the scene.

Investigators are now working to determine exactly how that blaze started.
