In Paraguay, authorities at the Minga Guazú Social Reinsertion Penitentiary Center discovered a grayish-white powder hidden within a double-bottomed thermos during a routine inspection. National Police explosives specialists conducted field tests on the substance, prompting officials to secure critical sectors of the facility. Subsequent security operations at the Minga Guazú center resulted in the seizure of weapons, cell phones, and the mysterious white powder. While preliminary field tests indicated the powder was not cocaine, the substance has been sent to a forensic laboratory to determine its exact composition and whether it possesses explosive properties. One mobile device was notably discovered hidden inside a Bible. Recent security raids targeting high-danger and maximum-security modules at the center resulted in the seizure of additional cell phones, weapons, and lighters. The investigation into the unidentified powder remains ongoing as forensic analysis continues. ## Timeline ### 2026-08-26: Guatemala and Paraguay prison raids uncover tunnels and contraband Security forces in Guatemala and Paraguay conducted major prison raids, uncovering an escape tunnel in Pavón and seizing contraband, including cell phones and unidentified substances in Minga Guazú. 19 sources. https://clstr.news/cluster/guatemala-authorities-thwart-escape-tunnel-construction-at-pavn-prison ### 2026-08-22: Minga Guazú prison officials find suspicious powder in hidden compartment Explosives experts were called to the Minga Guazú prison in Paraguay after a suspicious grayish-white powder was found hidden in a double-bottomed thermos brought in by a visitor. 3 sources. https://clstr.news/cluster/minga-guaz-prison-officials-find-suspicious-powder-in-hidden-compartment --- Cite as: Prison security operations in Paraguay.
