Joint police efforts led to the arrest of one suspect who police believe to be behind the attack in Berlin. The suspect, a Czech national, is currently being held in Prague for interrogation. During a press conference the ministers of the interior of Germany, the Czech Republic and Poland stated, that police believe that a right-wing extremist network is behind the attack in Berlin. The bomb was supposed to be a statement against the refugee policy of the EU and Germany, who agreed to take in many refugees from Cape Verde in a streamlined asylum application process. There are five additional main suspects, who are still on the loose. Two of these subjects are of polish origin and three are German citizens. An international arrest warrant has been issued, and police believe that it is just a matter of time until the suspects are caught.
