Officials are investigating yet another explosion at a former Army base in the ArkLaTex. It happened at Camp Minden Tuesday morning at 8:36 a.m. inside of an area known as "Area G," owned by GOEX Powder. The company makes black powder used by the military and also used for fireworks. According to GOEX officials, it was a small explosion that started at an unmanned machine. GOEX COO Tim Vaitekumas says there was no fire and minimal damage. No injuries were reported. It's the second explosion at Camp Minden in less than a month. On October 15, a blast in an underground bunker owned by Explo, Inc. shook the area, shattering windows in homes and businesses up to a few miles away. Officials are drawing no connection or similarities between the two incidents. The military, ATF and Louisiana State Police are involved in the investigation. They are waiting for the smoke to clear inside the building before they can get in and take a closer look at what happened.
