The FBI is offering a $10,000 reward to help retrieve an assault-style weapon, a handgun and other equipment that was stolen July 10 from an agency vehicle that was parked along the H Street corridor in Northeast Washington.

Authorities said that the vehicle — a Ford Expedition — was locked and that someone smashed a rear window and took a secured gun lock box. The agent reported the missing items to police about 7:50 a.m.; the FBI said they think the break-in occurred between 12 a.m. and 2 a.m.

The missing items include a Rock River Arms LAR-15 rifle, similar to an AR-15; a Glock-22 handgun; a holster; a collapsible baton; pepper spray; two boxes of .40 caliber ammunition; protective head and eye gear; and a black TruckVault gun box.

Also in the box was a Motorola radio. The FBI says that after the theft, the channels were descrambled, rendering the radio useless.

The FBI said in a statement that its agency along with D.C. police are “working to locate these weapons and remove them from the possession of the untrained individuals who may have them.”

Anyone with information about the weapon or other items is urged to call the FBI’s Washington field office at 202-278-2000.
