Japan ordered a North Korean freighter Tuesday set to carry goods to the North -- in place of a North Korean ferry at the center of arms and espionage allegations -- not to leave port.

The 298-ton freighter Namsan 3, which arrived at Maizuru port in Kyoto Prefecture at around 7:30 a.m. with 16 crew members, was to sail again in the afternoon.

But a special government probe concluded that the vessel must be detained in the Sea of Japan port because it does not have a marine chart of the surrounding area, local transport bureau officials said.
