On August 7, 2024, one day before the first concert was scheduled to begin, authorities arrested Beran A in connection with the terror plot. After discovering the alleged plot, Taylor and her team, Barracuda Music, cancelled all the Vienna performances at Ernst Happel Stadium and said they would no longer perform there, citing the tragic attack at Ariana Grande’s 2017 Manchester show and prioritising fan safety. The 3-night concert in Vienna was expected to attract more than 170,000 fans.
