JAPANESE FISH CREW INTERNED

SAN JOSE, Coast Rica, Saturday, Dec. 13. -- (AP) -- The Japanese crew of a motorized fishing vessel flying the Stars and Stripes was interned today, driven to dock at the Pacific port of Puntarenas by warning bombs which the Costa Rican government said were dropped by United States Navy patrol planes.

The fishing boat was identified officially as the Albert.

Explosion of the bombs -- loosed by a three-plane formation as the aerial equivalent of shots across the bow --startled Puntarenas residents yesterday. They first believed it signified an Axis attack.

The Albert had sailed into Puntarenas yesterday and then moved on to nearby Caldera to take on fuel oil.

The vessel was pulling away from Caldera when the plane patrol (presumably on guard against submarines and vessels which might refuel them roared into action. The helmsman quickly headed towards shore.

The crew was taken into custody under regulations implementing Costa Rica's declarations of war against Japan, Germany and Italy.

Mexico announced that two Japanese fishing boats had been seized on charges of illegal fishing off strategic Lower California, and similar seizures were reported on Cuba's northwestern coast.
