The Algerian suspect was the subject of an extradition warrant issued by Algerian authorities.
Morocco’s General Directorate of National Security (DGSN) said that the suspect was wanted for his suspected links to a criminal network active in drug and psychotropic tablet trafficking.
The operation, according to DGSN, is part of international cooperation to ensure security.
Moroccan police placed the suspect in custody for further investigation before studying the extradition request.
Morocco’s preliminary investigation indicated that the suspect was involved in a criminal network that forged identity documents and passports.
The network, which was helping Algerian nationals get Moroccan documents, was dismantled in Oujda in 2018, according to DGSN.
The Moroccan security services arrested four other Algerian nationals who obtained counterfeit Moroccan identity documents, added DGSN, noting that the arrested individuals were brought to justice.
