A Korean-American man who served prison time for trying to broker the sale of sarin nerve gas bombs to Iran has been indicted on charges of attempting to export advanced rocket technology to South Korea.
The federal indictment filed Wednesday in Miami charges 68-year-old Juwhan Yun (Joo-‘WAHN Yun) of Short Hills, N.J., with illegally trying to arrange a deal for rocket propulsion systems for a South Korean satellite launch vehicle.
Yun was convicted in 1989 of conspiracy involving the nerve gas plot and served about two years in prison.
The new charges carry a maximum sentence of 60 years. Yun’s attorney and the South Korean embassy in Washington did not immediately return calls seeking comment. Yun was arrested April 15 and is being held without bail.
