LA PAZ, Bolivia (AP) — Bolivian prosecutors say they will seek Interpol's assistance in arresting six South Korean businessmen who Bolivia alleges were paid $30 million for 16 motorized launches that were never delivered to its navy.

Two Bolivian officials are under arrest in the case, charged with causing economic damage to the state.

Bolivia alleges the South Koreans arranged to have the launches and two tugs built in China, but the vessels were never delivered and Chinese officials sued Bolivia for storage fees.

Bolivia is landlocked. Its navy patrols Lake Titicaca and eastern rivers.
