The ministry said yesterday that senior prosecutor Choi Jae-kyung of the Seoul District Prosecutors` Office is investigating the document.

Names of people Kim met in U.S. federal prison before his extradition to Korea are on the record. A political bombshell is expected if Korean intelligence officials or politicians are mentioned.

After the record is analyzed, Kim will be grilled on why he gave up fighting his extradition to Korea.

He has refused to appear for questioning, citing his right to silence. “I want the independent prosecutor team, not the prosecution, to investigate me.”

In addition, prosecutors have summoned a “Shin” who stayed in the same prison as Kim and people close to Shin.

Shin said, “I heard Kim is getting help from an unknown official in an executive position who was sent to the Korean consulate-general in Los Angeles, and I know that the official’s successor contacted Erika Kim, Kim Kyung-joon’s sister.”

The National Intelligence Service, however, denied the allegation, saying, “We also conducted our own investigation and none of our officials were involved.”
