Two people seriously injured in a Dortmund gym. Three men provisionally arrested.

Investigators suspect a targeted attack behind the crime. This is reminiscent of the bloody deed in a Duisburg gym a month and a half ago. In that case, there are indications of a terrorist motivation in his case. So far there are no signs of a similar situation in the Dortmund case.. An arrow points the way to the emergency room of a hospital.. The Office of the Attorney General of Switzerland had taken over the investigation.
