Police chose not to close down the event, fearing that doing so could spark another panic. Nearby motorway A59, which was closed during the whole Love Parade, functioned as an access route for emergency services. During a press conference on 25 July, organiser Rainer Schaller stated that there would never again be another Love Parade, out of respect for those who lost their lives, and the festival was permanently cancelled.
