A Florida man has been arrested after a live grenade was found in his pickup truck during a traffic stop, according to the Flagler County Sheriff's Office.

Louis Branson, 65, was charged with driving with an expired license for more than six months and possession of drug paraphernalia, First Coast News reports.

Deputies said they made contact with Branson and asked him to provide his driver’s license. Upon questioning, it was determined Branson was aware that his license was expired for more than six months, and he was arrested without incident.

Deputies say they also found a device appearing to be a grenade in the vehicle. Branson stated he had cleaned out a veteran’s home and found the grenade and decided to keep it. He was reportedly unaware if it was active or not.

After conducting an investigation, including an x-ray of the device, it was believed to be a real grenade based on the x-ray revealing its internal mechanisms. The grenade was removed from the vehicle and safely detonated by at a nearby county-owned facility.
