A 26-year-old man, considered violent and wanted by the German authorities, was detained by the SEF at Porto airport.
The arrest was followed by a European arrest warrant for extradition issued by Germany.
The individual is indicted in that country for the crimes of robbery and fraud of telecommunications companies.
“He was arrested at Francisco Sá Carneiro Airport this morning and present to the Public Prosecutor’s Office at the Oporto Court of Appeal. The court applied the preventive custody measure in order to await possible extradition,” the SEF said in a statement
