Over 200 officers took part in a series of pre-dawn raids across Germany on Wednesday as authorities seek to foil a major international migrant trafficking ring.
Seven apartments and business premises were searched in the German states of Berlin, Saxony, Bremen and North Rhine-Westphalia, according to federal police spokesman Christian Meinhold.
The raids saw two men detained in Berlin, while another man was arrested in the Saxon town of Bad Muskau, located on the border with Poland. The men are reported to be Turkish, Polish and Bulgarian nationals.
