The threatening letter Seda Basay-Yildiz pulled out of her fax machine on August 2 was worse than the usual one. The Frankfurt lawyer defends, inter alia, the alleged bin Laden bodyguard Sami A. and represented victims of the NSU in court, hostility from the right belong to their business.

But the fact that the "NSU 2.0" announces its "slaughter" her daughter, and that she must read next to the name of the two-year-old and her home address, went well beyond the usual measure. Basay-Yildiz filed a complaint - possibly exposing a right-wing extremist cell to the Frankfurt police.

"I could not explain where the author of the letter got these data from, so I turned to the police," said the lawyer for the "Frankfurter Neue Presse". As the newspaper writes, the investigators had met in the course of their investigations on a group of five police officers of the first area, against which now runs criminal proceedings. In addition, disciplinary action is also taken against them.

In fact, it turned out that the registration records for Basay-Yildiz had been interrogated by a computer in a city guard, apparently for no official reason. The police, who had access to the computer at the time in question, then came under the spotlight of investigating state protection. The workplaces of the four police officers and a policewoman were searched, cell phones and hard drives confiscated.

During the evaluation of the devices, the state guards came across a WhatsApp group, about which the "Frankfurter Allgemeine Zeitung" first reported on Monday. Over the group chat, the suspects apparently wrote and read xenophobic news for weeks, sent Hitler pictures and swastikas. To what extent exactly is still unclear. Supposedly, apart from right-wing comments, "other topics" have also been exchanged.

The initial suspicion against the four policemen and their colleague is at least: incitement and use of symbols of anti-constitutional symbols. Whether also because of the threatening letter against the five policemen is determined, the "Frankfurt new press" could not bring in experience. "For tactical reasons," as the police say.

Frankfurt's chief of police Gerhard Bereswill had announced on Wednesday in an interview with the "FAZ" a "hard course" against officials of his authority, which were not on the ground of the Constitution. If the allegations against the suspects prove, they would be removed from the service. So far, the five police officers are only suspended.
