Vienna police detained 2 people allegedly "planning an attack" on some events, including Swift's concerts.
"For everyone's safety, we have no choice but to cancel the 3 planned concerts," the organization organizing the concerts, Barracuda Music, said on its social media account.
In the statement, it was stated that concert tickets will be refunded within 10 working days.
Franz Ruf, Director General of the Austrian Public Security Unit, stated that they were aware of the acts of preparation for a possible attack and claimed that one of the detained suspects was linked to the terrorist organization ISIS.
