The Federal Criminal Police Office is alarmed and fears that the criminals could obtain sensitive information from security authorities.The documents for the security service originate from a confidential Federal Criminal Police Office paper, as the magazine reports. According to the magazine, buildings in which the forces of a Special Operations Command (SEK) and a Mobile Operations Command (MEK) were housed were also affected.According to the report, the Federal Criminal Police Office warned in its analysis that there was a danger that criminals would "observe police tactics at first hand".
