Judicial investigators said Wednesday that three customs inspectors at Juan Santamaría airport were shaking down arriving air travelers.
Agents arrested three customs employees, all in their 50s, at the airport and a fourth man who worked as a baggage handler, said the Judicial Investigating Organization.
The crimes alleged date back to 2014.
The investigating agency said that the customs inspectors would tell arriving travelers that they carried baggage that weighed too much. Then they threatened to confiscate some of the luggage or packages.
The air traveler victims were extorted for sums ranging from $70 to $160, said the judicial agency.
