Germany’s federal prosecutors say a second person detained in connection with the deadly car-ramming attack during Berlin’s Pride celebrations over the weekend has been released. In a statement to Reuters on Monday, the prosecutors’ office said it continues to investigate broadly and declined to provide further details.

Both outlets report that the release follows earlier investigative steps in which authorities detained the person on suspicion related to the attack. Spiegel, as cited by the other outlet, reports that officials decided to release the suspect because initial suspicions that he was a passenger in the vehicle at the time of the attack could not be sustained.

The prosecutors do not comment beyond stating that the investigation is ongoing. The available reporting focuses on the change in detention status and the prosecutors’ continued investigation rather than on further allegations, motives, or additional evidence.
