A Nicaraguan man who lives in Costa Rica became a victim of the efforts by frontier police to tighten border controls.
Officers said the man crossed into Costa Rica at a point in Los Chiles that is not designed for traffic in an attempt to evade inspection. The man carried nearly 600 small fish that appear to have come from the Río San Juan.
Officers confiscated the fish as illegal imports, but the man still had problems.
Officers said his vehicle had not been inspected and the driver had not paid the annual marchamo or road tax. Traffic police were called.
