A penalty order against Zverev was issued this month in Berlin for him physically harming the mother of his child. the application by the prosecutor was already reported a few months back, now the district court granted it. In German law this essentially means that the evidence is so overwhelming that no trial is deemed necessary to penalize the suspect. However, he will appeal it and a public trial is likely now. He is still presumed innocent.
Interestingly the incident was in May 2020 (they seperated pretty soon after this). Their child was born 11 march 2021.
I hope over this case that also for his other ex-girlfriend, that he likely assaulted, justice will be served in a way even if not legally, but I doubt ATP will bat an eye.
Edit: english speaking report on this matter
