Initial suspicions regarding the second suspect’s involvement were not substantiated, leading to his release from police custody. The primary assailant, a 21-year-old German citizen of Lebanese descent, was shot dead by police after he attacked officers with a knife following a vehicular assault on a crowd during the CSD event, resulting in one fatality and 29 injuries. Federal Interior Minister Dobrindt classified the incident as an Islamist terrorist attack and called for a review of security measures at large events.
