Immigration police detained members of a group who are suspected of forging work documents for Nicaraguans.
Three persons, including a man identified by the last name of Hoffman, were seized Thursday in a house in Tibás, San José. Agents suspected that they would be making documents at 10 a.m. that morning, according to immigration.
One of the other persons was identified by the last name of Garcia. The last member is only known by the name Victor, spokespersons said.
The group has been under investigation since January, after investigators were given information about a counterfeiting scheme.
Each permit was sold to a Nicaraguan for 40,000 colons. Victims were told that the documents came from the Dirección General de Migración y Extranjería, a report said.
A raid of the house resulted in the police acquiring computers, printers and plastic cards.
