A 24-year-old Heredia resident has been identified as a suspect in creating and distributing malicious computer programs.
He was detained in his home in Barreal de Heredia, said the Judicial Investigating Organization.
The agency said that it was working on a tip from the U. S. Federal Bureau of Investigation that identified the man though the Internet address he was using.
That led to Costa Rica, said the judicial agency.
The FBI is in the process of seeking the arrest of 30 persons in various parts of the world for the same reason, according to the Judicial Investigating Organization.
Computers and other electronic equipment were confiscated, the agency said.
As a Costa Rican, the man cannot be extradited to the United States, but he can be tried here.
The exact natures of the operation was not given. Usually individuals with this type of activity work as groups. The malicious software is believe to be the type that can take over computers and send unsolicited emails to many persons. The captured computers also can be used as a weapon to disable target computers with massive amounts of data.
