According to the Stars and Stripes (October 28, 2012):

A South Korean man has been charged with fraud for allegedly impersonating a U.S. military officer and promising to introduce merchants outside two major USFK bases to a new source of clients — American troops.

An officer in the criminal investigations unit for the Gyeonggi Provincial Police Agency said the man, identified only by his last name of Lee, visited a number of stores, bars, hotels and car dealerships near Osan Air Base and U.S. Army Garrison Humphreys in August and September and tried to pass himself off as a U.S. Army major.

Two storeowners in Pyeongtaek, including an import-car salesman, paid Lee 19 million won — about $17,300 — for his promise to send U.S. Forces Korea servicemembers to their businesses, the police officer said. Lee, who is in his late 30s, also did not repay money he borrowed from other businessmen so he could buy real estate.

And it wasn’t just in the Osan area

Lee has been previously convicted for fraud, and before his arrest this month was wanted for six other crimes, including two cases of fraud in Seoul, one in Jeju Island, and one in Dongducheon, home to the 2nd Infantry Division’s Camp Casey.
