(NBC) - Officials in Forth Worth, TX want to find two men who intentionally set a building on fire.
The arsonists were caught on surveillance video. In it, you can see the crime from start to finish. A pickup truck pulls up to the building in the 2900 block of Alta Mere, and a suspect wearing a mask starts tossing buckets of liquid that splashes all over the place.
Eventually six buckets of fuel are spilling across the pavement and a second person sets two propane tanks against the front of the building.
Finally, one of the men tosses what appears to be a burning flare and the place goes up in flames.
Three firefighters were injured fighting the intense flames; two firefighters were trapped under burning debris for several minutes, which means more serious charges for the suspects.
But first, investigators must find them.
