Montgomery County Man Charged With Impersonating an FBI Agent

PHILADELPHIA - United States Attorney David Metcalf announced that Seok Joon Lee, 54, of Jenkintown, Pennsylvania, was charged by indictment with impersonating a federal officer, and acting as such.

The indictment alleges that, on or about April 22, 2026, the defendant falsely assumed and pretended to be an agent and employee of the FBI, in that the defendant entered a Philadelphia supermarket wearing a bulletproof vest, a law enforcement-type duty belt, a holstered firearm loaded with 13 rounds of live ammunition, and two spare magazines, identified himself as an FBI agent to a security guard, and attempted to conduct a security check of the supermarket. Lee subsequently stated to responding officers from the Philadelphia Police Department that he was "undercover FBI" and that his credentials and FBI number could be located elsewhere.

If convicted, the defendant faces a maximum possible sentence of a monetary fine and three years in prison.

This case was investigated by the FBI, Bureau of Alcohol, Tobacco, Firearms, and Explosives, and the Philadelphia Police Department and is being prosecuted by Assistant United States Attorneys Michael R. Miller and Nelson S.T. Thayer Jr.

The charges and allegations contained in the indictment are merely accusations. Every defendant is presumed to be innocent unless and until proven guilty in court.
