Three Immigration officials accused of forming a corrupt network that falsified documents to slip people into the country were arrested yesterday, according to a statement from the Judicial Branch.

An investigation carried out in San José, Alajuela and Naranjo, both to the northwest, revealed that these officials modified the records of foreigners who had been denied Costa Rican residency because of “doubtful reputations,” mostly Colombians, the statement said.

Police yesterday raided these officials' homes and seized photocopies of falsified Immigration records. They are accused of information sabotage, bribery and conspiracy. The Prosecutor's Office is requesting preventive detention.
