A U.S. citizen surnamed Kjar-Arnbal was deported to the United States, confirmed the Costa Rican General Directorate of Migration.

A couple of weeks ago, Kjar-Arnbal, was detained during a road surveillance operation that took place in La Sabana Canton, San José.

The U.S. citizen had no legal record of entering the country. Also, he had an international arrest warrant issued by the U.S. State of Mississippi for allegedly committing the crime of selling a substance known as MDMA, more commonly known as ecstasy or molly.

The expat also had served a sentence for an infraction of the Psychotropic Law in Costa Rica, Migration said.

MDMA is a synthetic drug that acts as a stimulant and hallucinogen. It produces an energizing effect, distortions in time and perception, and enhanced enjoyment from sensory experiences. It has also been described as an entactogen, a drug that can increase self-awareness and empathy, said the U.S. National Institute on Drug Abuse.

Kjar-Arnbal was taken from the Immigration Apprehension Center in San José to the Juan Santamaria International Airport (SJO) in Alajuela Province where he was assigned to the U.S. authorities.

As of May, Migration has deported 228 foreigners of nationalities such as Nicaraguan, Salvadoran, Colombian and U.S.

According to the U.S. Embassy, in the case of the arrest of a U.S. citizen,  the guidelines include a consular officer visiting an arrested person after being notified by Costa Rican authorities to ascertain the arrestee’s physical well-being and conditions of arrest, provide information on legal procedures, including a list of attorneys, and, if the prisoner wishes, notify family or friends.
