SEATTLE — Sokphana Soeung, 42, of King County, appeared in federal court after being charged with unlawful possession of a destructive device following a slow-speed chase and a confrontation with law enforcement, federal prosecutors announced Monday.
The incident began on October 12, 2024, when Bellevue Police responded to reports of two men sleeping in a car with the engine running at Enatai Beach Park. When officers approached, Soeung drove away, running over spike strips that punctured all four tires. A slow-speed chase ensued, involving the Washington State Patrol (WSP) as Soeung’s car moved westbound on Interstate 90.
On Mercer Island, a WSP trooper successfully executed a maneuver to stop the vehicle. Soeung exited the car holding a black ball-shaped object in one hand and a lighter in the other. Officers tackled him, causing him to drop the item and lighter. Authorities determined the object to be a tennis ball filled with explosive powder and a fuse. A search of the car uncovered a second explosive device made from sparklers taped together.
The incident prompted a temporary shutdown of I-90 while bomb squad units ensured there was no threat to the public or the bridge.
The second person in the car exited before Soeung and was detained for questioning. That individual denied any knowledge of the explosive devices.
Soeung, who has been in custody since his arrest, faces up to 10 years in prison if convicted of unlawful possession of a destructive device.
The case is being investigated by the Bellevue Police Department, Washington State Patrol, and the Bureau of Alcohol, Tobacco, Firearms and Explosives (ATF). Assistant U.S. Attorney Cecelia Y. Gregson is prosecuting the case.
Soeung’s arrest underscores the serious consequences of possessing and transporting explosive devices in public spaces.
