These attacks led to an increase of tensions, which reached their climax the night of 11 December, when an explosive device was ignited outside the concert venue. Although IDS MP Damir Kajin accused Thompson's fans, it turned out that the offender, Vilim Bon (then aged 59), who was injured in the defragration and arrested by police, was acting to stop the concert.
