SAN JOSE, April 25 (Xinhua) -- Costa Rica's Foreign Ministry on Friday expressed its protest to the United States following the detention of the country's general prosecutor.

    Francisco Dall'Anesse was detained at Miami airport on April 23when he was about to enter the United States on an official trip.

    "With this strong protest, (Costa Rica's) Foreign Ministry echoes the disagreement of the people and government of Costa Rica. This aggression against our general prosecutor is an affront to all Costa Ricans," said the protest note.

    Costa Rican Foreign Minister Brugno Stagno on Friday handed over the protest note to Peter Brennan, the business representative of the U.S. Embassy in San Jose.

    Dall'Anesse was "inexplicably" detained and "treated unfairly and disrespectfully," said Stagno.

    Invited by the general prosecutor of the United States, Dall'Anese was on his trip to attend two prosecutors' meetings before he was detained.

    "This episode is one of many reiterated incidents affecting Costa Rican officials and it reveals the United States' serious disrespect of international juridical regulations. This attitude, evidently, does not contribute to strengthening friendship and cooperation in the framework of mutual defense before common threats," stated the protest note.

    Costa Rica demanded those who detained Dall'Anese be made legally responsible as well as indemnification of the expenses caused by the incident.
