In the process of the deadly knife attack of Chemnitz, the witness Yousif A. made his statement dependent on the expulsion of the prosecutor. He wanted to testify as a witness in court, let the former in the case suspects tell his lawyer Ulrich Dost-Roxin. But he could not do so in the presence of public prosecutor Stephan Butzkies, because he sees in this a "maximum of bias".

Yousif A. had been in custody from 27 August to 18 September and was released on suspicion of lack of suspicion. Meanwhile, the investigation against the Iraqis have been set. He reported to Butzkies for infringement and deprivation of liberty. The arrest warrant had been "completely groundless, arbitrary and unlawful", it was said. The Chamber interrupted the interrogation. She wanted to check the explanation and then make a decision.

Since March 18, the Syrian Alaa S. has been responsible for joint manslaughter before the Regional Court Chemnitz. He is said to have stabbed 35-year-old Daniel Hillig on August 26, 2018 in Chemnitz with Iraqi Farhad A., who is still on the run. After the fact, there were demonstrations and riots in the city, some of them far-right groups, because the suspects were asylum seekers.
