A Metropolitan Police Department (MPD) sergeant was arrested last night after crashing his vehicle into a car carrying federal agents, and was discovered to be armed with a machine gun and a cache of unregistered firearms.
The suspect, Sgt. Montez Clark (age 27), was driving a blue Chevrolet Camaro when District and federal law enforcement officers attempted to stop the vehicle for what they described as an equipment violation, according to NBC Washington.

Rather than comply, Clark allegedly fled, colliding head-on with a vehicle carrying three Diplomatic Security Service agents.
Once the vehicle was immobilized, federal and local officers say they discovered a terrifying arsenal: two Glocks, one equipped with a “switch” converting it into an automatic machine gun, plus multiple types of unregistered ammunition and high-capacity magazines.
Clark, along with two passengers identified as Sakou Yates (25) and Russell Campbell (23), were taken into custody. Charges against Sgt. Clark reportedly include:
- Assault on a federal law enforcement officer
- Fleeing law enforcement
- Leaving after colliding
- Possession of a machine gun
- Possession of unregistered firearms and ammunition
- Carrying a pistol without a license
- Violation of the National Firearms Act
- Possession of a large-capacity ammunition-feeding device
- Related firearms violations
Campbell faces an additional count of being a felon in possession of a firearm, according to WJLA.
MPD has placed Sgt. Clark on administrative leave while the department’s Internal Affairs Bureau opens its own investigation.
