A residential property in Dublin was also searched following a request by the Spanish authorities.
The search in Dublin was carried out by gardai attached to the GNBCI.
An officer from the Guardia Civil attended the search and was supported by the Criminal Assets Bureau (CAB) and the Emergency Response Unit (ERU).
Wednesday’s operation is part of ongoing liaison between the GNBCI and Guardia Civil in Spain, which is targeting a transnational organised crime group.
A previous search targeting the same group was carried out in Lanzarote in June 2022 by Guardia Civil on behalf of GNBCI.
The Hutch crime gang is a international drug-dealing gang based in Ireland.
Gardai said investigations are ongoing.
