Organizers have cancelled three concerts for American music star Taylor Swift in the Austrian capital Vienna after authorities announced the arrest of a suspect who plotted an apparent terror attack at the events.

Swift was scheduled to perform at the Ernst Happel Stadium on Thursday, Friday and Saturday as part of her Eras Tour.

But on Wednesday, local security agencies arrested two individuals suspected of plotting attacks, purportedly influenced by the Islamic State group, targeting major events in Vienna.

“With confirmation from government officials of a planned terrorist attack at Ernst Happel stadium, we have no choice but to cancel the three scheduled shows for everyone’s safety,” Barracuda Music, one of the organizers of the events, posted on Instagram.

The singer’s website added that all tickets will be automatically refunded within the next 10 business days.

A 19-year-old Austrian man was arrested in Ternitz, located approximately 40 miles southwest of Vienna in what the authorities term as a counterterrorism operation. The second suspect was apprehended in the capital.

In a social media statement, Austrian Chancellor Karl Nehammer expressed that “the cancellation is a bitter disappointment for all fans in Austria, the situation involving the purported terrorist plot in Vienna was extremely serious.”

He emphasized the gravity of the circumstances and the safety concerns necessitated the unfortunate but necessary decision to cancel the event.

The three Vienna shows of the “Eras Tour” were sold out, with approximately 170,000 people expected to attend.

In November 2020, Vienna was the target of a terrorist attack that left four people dead.
