Taylor Swift terrorist threat suspect confessed he intended to kill fans: Officials

A suspect accused of plotting a terrorist attack at Taylor Swift's concerts in Vienna intended to kill "as many people as possible" outside the stadium, according to officials.

The 19-year-old Austrian, who police arrested on Wednesday in connection with the foiled plot targeting a Swift show at Ernst Happel Stadium, had planned an attack on fans involving "bladed weapons as well as the construction of a bomb," according to a press release provided by the Vienna Federal Ministry of the Interior on Thursday.

During a search of the suspect's home, officials found "chemical substances, liquids, explosive and technical devices that could be used to manufacture explosives," said Franz Ruf, director general for public security. Bomb-making instructions and machetes were also found.

"He wanted to carry out an attack in the area outside the stadium, killing as many people as possible using the knives or even using the explosive devices he had made," according to national intelligence head Omar Haijawi-Pirchner.
