MEMPHIS, Tenn.– A woman was arrested after Mississippi authorities say they found a homemade explosive device in a suspicious package.

On Aug. 4, a federal search warrant was conducted by ATF, Panola County Sheriff’s Office, Tupelo Bomb Squad and the Mississippi Bureau of Narcotics at a residence on Highway 35 South in Panola County.

During their search, they said they discovered bomb-making materials homemade high explosive substances, firearms, narcotics and an explosive device found inside of the home.
