The most discussed concert was the first ever banned in Croatia, in the Istrian town of Umag. After this ban, Thompson asked for permission to hold a concert in Pula, Istria's most populous city. When this was denied, the band initiated and lost court actions against the city of Pula for "human rights violations". After the court decision, the band's lawyer declared that sooner or later Thompson would perform in Pula. In late December 2008, he managed to secure permission to organize a concert in Pazin, despite fierce opposition from the Istrian Democratic Assembly, the region's leading political party. 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. The concert took place as planned on 20 December 2008, followed by two more shows on 21 and 22 December due to reported demand.
