Uganda-CJNG Arms Case: Retired Officer's Extradition Exposes Africa's Widening Role in Cartel Networks

A Ugandan national has been handed over to United States authorities, closing out a 14-month legal saga that began with a Drug Enforcement Administration sting operation and ends with a case that stretches from Kampala's military and political elite to the heart of one of Mexico's most feared cartels.

Katungi Michael Mpeirwe, a retired lieutenant in the Ugandan army, was extradited to the US following his arrest in Kampala earlier this year. Ugandan prison authorities confirmed the handover after the Buganda Road Chief Magistrates Court cleared the way for his surrender, rejecting a series of preliminary objections his defence team had raised, including a claim to diplomatic immunity drawn from his earlier service as a deputy head of mission.

US prosecutors in the Eastern District of Virginia allege that Mpeirwe conspired with three co-defendants Bulgarian national Peter Dimitrov Mirchev, Kenyan national Elisha Odhiambo Asumo, and Tanzanian national Subiro Osmund Mwapinga to procure and supply millions of dollars' worth of military-grade weaponry.

The indictment lists machine guns, rocket launchers, grenades, anti-personnel mines, night-vision equipment, sniper rifles, drones, and surface-to-air and anti-aircraft systems, including the ZU-23 anti-aircraft gun.

Some reporting places the value of the alleged arms package at roughly $58 million.

The intended buyer, according to the indictment, was Cártel de Jalisco Nueva Generación (CJNG) a group Washington has designated both a Foreign Terrorist Organization and a Specially Designated Global Terrorist entity, and which US officials describe as among the most violent and prolific transnational criminal organisations operating today.

Court filings allege the conspirators also discussed cocaine trafficking tied to the cartel's broader operations, and that they sought fraudulent end-user certificates to disguise the true destination of the weapons a familiar tactic in grey-market arms diversion schemes that African security analysts have flagged for years.

A Politically Sensitive Arrest
What elevates this case beyond a routine arms-trafficking indictment is Mpeirwe's political proximity to power in Kampala. He served as external affairs commissioner and a member of the Central Committee of the Patriotic League of Uganda (PLU) the political vehicle associated with Gen. Muhoozi Kainerugaba, Uganda's Chief of Defence Forces and son of President Yoweri Museveni, widely seen as positioning himself for eventual succession.

Kainerugaba moved to fire Mpeirwe from the PLU only after the US indictment became public in mid-2025.

That proximity forced Uganda's judiciary into a delicate balancing act. The extradition proceedings dragged through objections over ministerial authority, the role of the Solicitor General and the Director of Public Prosecutions, and procedural questions about how the case was initiated all of which Chief Magistrate Ritah Neumbe Kidasa ultimately dismissed, finding that Kampala had met the evidentiary threshold required under Uganda's Extradition Act and its obligations under the 1988 UN Convention Against Illicit Traffic in Narcotic Drugs and Psychotropic Substances.

The West African Thread
For readers across Ghana and the wider West African security community, the case carries a more immediate resonance than its Kampala datelines suggest. The broader investigation codenamed Operation Take Back America relied on cooperation from authorities in Spain, Morocco, Greece, and Ghana.

Mirchev was arrested in Madrid; Asumo was picked up in Casablanca; and Mwapinga, the Tanzanian co-defendant, was detained in Accra and has already been extradited to the United States.

That Ghana served as an arrest point in a DEA-led network spanning three continents is a reminder that West Africa's exposure to transnational arms and narcotics networks is no longer confined to the familiar Sahelian corridors of jihadist financing.

The same logistics chains, false-documentation schemes, and intermediary networks that move weapons and narcotics through the region's ports and land borders are increasingly interoperable with criminal enterprises as geographically distant as Jalisco.

What Comes Next
Mpeirwe now faces a three-count US indictment covering conspiracy to distribute cocaine, conspiracy to possess firearms including a machine gun and destructive devices in furtherance of drug trafficking, and conspiracy to provide material support to a designated foreign terrorist organisation. Convictions on these counts carry a minimum of ten years and can extend to life imprisonment.

The case will likely be watched closely in both Kampala and Washington in Uganda, for what it signals about the willingness of a government closely tied to the Museveni-Kainerugaba political axis to cooperate with US law enforcement against one of its own; and in Washington, as a test case for how aggressively the DEA and DOJ intend to pursue African nationals implicated in cartel supply chains.

For West African governments, including Ghana's, it is also a quiet signal: the region's ports, transit routes, and diaspora networks remain attractive terrain for criminal actors operating far outside the continent, and the cost of looking the other way is rising.
