Four thieves are reportedly on the loose after a brazen don't-blink-or-you'll-miss-it gun store burglary in Zephyrhills, Florida.

The four struck early Sunday, using a stolen truck from Pinellas County to obliterate the entrance of the Sunshine State Armory, police said. Incredible surveillance video shows thieves piling in behind the truck, smashing glass cabinets and stealing guns from the store. Police said the incident took all of 31 seconds.

The thieves then drove the stolen truck about a mile away from the crime, setting fire to it aside some railroad tracks alongside a mobile home park, and presumably switching cars, police said.

The thieves left ammunition in the truck, which went off as the fire spread, police said. Fire crews had to wait for the fire to go out before securing the scene, and one witness interviewed by WFTS said the fire and ammunition going off reminded him "of Vietnam."

Police are offering a $2,500 reward to anyone with information about the crime. Guns from similar burglaries – many of which happened in the Tampa Bay area – have turned up at murder scenes and other crimes. Police have not released information about how many guns were taken.
