The suspect, who was reportedly seen leaving the scene of the attack, was released from police custody after media reports confirmed the lack of evidence against him. The primary assailant, a 21-year-old German citizen of Lebanese descent, was shot dead by police after he allegedly drove a vehicle into a crowd and subsequently attacked individuals with a knife, resulting in one fatality and 29 injuries. Federal Interior Minister Dobrindt classified the incident as an Islamist attack and called for a review of security measures at large events, emphasizing the need for heightened vigilance against potential copycat incidents.
