After the anti-terrorist operation in Castrop-Rauxel in the Ruhr area, the police are investigating at high pressure, according to North Rhine-Westphalia's Interior Minister Herbert Reul (CDU). "We had a serious tip that prompted the police to intervene that night," Reul told the German Press Agency on Sunday morning. Now the results of the investigation have to be awaited.

On Sunday night, emergency services arrested a 32-year-old Iranian who is said to have prepared an Islamist attack. According to the Düsseldorf public prosecutor's office, the man is suspected of having bought the toxins cyanide and ricin. It was initially unclear how far the attack plans had progressed and whether there was already a concrete target for the attack.
