The Independent Corrupt Practices and other Related Offences Commission (ICPC) said it has recovered 372 international passports from fraudulent travelling agents.
A statement by the commission resident media consultant Mr Folu Olamiti said the recovery is part of an ongoing clampdown on corruption prone processes in the acquisition of visas.
He said that owners of these passports should come to the commission's headquarters in Abuja with proof of ownership and reclaim them. ICPC said it made several arrests after receiving petitions from prospective students seeking educational placement and patients seeking medical attention abroad who were duped by some agents.
The commission said it arrested 18 suspects involved in such scams in Abuja and Lagos in October last year. Three of the suspects were allegedly involved in the production of fake documents for visa requirements, while another person was found in possession of suspicious travel documents.
The commission had since last year issued a "visa scam press advisory" warning intending travelers of the consequences of patronizing and using dubious travel agents and touts to obtain visas through corrupt practices.
