Police thought they were dealing with another drug shipment at the border with Panamá Monday morning.
Someone off-loaded merchandise from a northbound bus before it reached Costa Rica, and the merchandise was taken into Costa Rica by smaller vehicles in an informal manner, that is without reporting the load to customs.
The merchandise turned out to be 640 baseball-type caps and 560 purple shirts. All had markings of an anti-cancer foundation in Costa Rica.
Smugglers tried to put the merchandise back on the bus at its first stop in Costa Rica, but police intervened. The man who appeared to be in charge of the load was a Panamanian citizen, police said.
