Investigators in Hong Kong indicted four people, including two Japanese, on Saturday for allegedly possessing fake U.S. government bonds and $100 notes, local newspapers reported Sunday.

Indicted were Shinri Nakamori, 44, Masahide Momohara, 47, along with a Japanese-American merchant and a Hong Kong real-estate agent, the newspapers said.

They were arrested Wednesday when the two Japanese and the U.S. merchant were found with 740 fake U.S. bonds, amounting to some $370 billion, in a Hong Kong hotel room. The real-estate agent visited the three at the room with 88 fake $100 notes, the papers said.

Information that fake U.S. bonds would be traded at the hotel led the authorities to arrest the group, said the report, adding that one of the four admitted that the group had planned to make a deal with a crime organization in Guangzhou, China.
