Spanish authorities have scrutinised the group over its anti-immigration rhetoric, particularly after thousands of migrants crossed in July into Ceuta, Spain’s North African enclave.Police also searched the group’s headquarters in Madrid and other locations. They said they seized more than 20 firearms, some of them unlicensed, along with large quantities of ammunition and other illegal weapons.The court said key members of the organisation had already been placed under precautionary measures, including a ban on leaving Spain and a requirement to report weekly to a court.Reuters also reported last month that Spanish police arrested three members of a far-right group in Madrid on October 3, after tens of thousands marched across the country over the housing crisis.The Spanish government said far-right activists, some performing Nazi salutes, tried to reach demonstrators camped in the Puerta del Sol square.
