Taylor Swift ISIS bombing suspect pictured holding dual knives as chilling details of terrorist plot revealed

The older teen had quit his job on July 25 and told people he had “something big” planned, while the 17-year-old recently broke up with his girlfriend, Ruf said.

The pair had also made contact with others who were apparently aware of the terror plot plans.

A 15-year-old boy was also taken in for questioning Wednesday after the sinister plans were uncovered, though it was unclear if he had been arrested.

Meanwhile, both older suspects had been under surveillance by Austrian authorities and were known risks before their arrests, officials said.

Investigators said they found extensive material related to ISIS and al Qaeda during a raid at the second suspect’s home.

The main suspect — who authorities say fully confessed to the attack plans after his arrest — had recently sworn allegiance to Islamic State’s leader online, security officials said.

The older suspect was “clearly radicalized in the direction of the Islamic State and thinks it is right to kill infidels,” said Omar Haijawi-Pirchner, head of the Directorate of State Security and Intelligence.

Haijawi-Pirchner added that the suspect “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.”

The names of those allegedly involved haven’t been released due to Austria’s privacy laws, and the 17-year-old suspect has reportedly refused to talk since his arrest.

Swift had been slated to play the three sold-out shows, which were expected to draw 195,000 people, Thursday through Saturday.

Nehammer defended the decision to nix the shows, saying they occurred too close to the arrests.

“I understand very well that those who wanted to experience the concert live are very sad,” the chancellor told a news conference Thursday. “Moms and dads are looking after their daughters and sons, who were full of enthusiasm and anticipation for this concert. But it’s also important that in such serious moments as now, it’s inevitable that safety comes first.”

It wasn’t immediately clear for which concert the thwarted attack was meant to target.

“The situation was serious, the situation is serious. But we can also say: A tragedy was prevented,” Austria’s Interior Minister Gerhard Karner said Thursday.

Event organizer Barracuda Music revealed in an Instagram post late Wednesday that “we have no choice but to cancel the three scheduled shows for everyone’s safety.”

It cited government officials’ confirmation of the planned attack at the stadium.

News of the terror threat — and subsequent cancellations — devastated “Swifties” across the globe.

Austria’s Vice Chancellor Werner Kogler said in a post in X: “For many, a dream has been shattered today. On three evenings in Vienna, tens of thousands of #Swifties should have celebrated life together.

“I am very sorry that you were denied this. Swifties stick together, hate and terror can’t destroy that,” Kogler wrote.

But some Swifties who had traveled to Vienna for the show were undeterred – with many turning out in the streets of the Austrian capital city to console each other over the near miss.

Filling the city streets by the hundreds, fans joined arms to belt out their favorite Swift songs together, swapped friendship bracelets, and shared group hugs.

Swift’s next shows, scheduled for August 15 through 20 in London, are expected to go ahead as planned.

“We’re going to carry on,” said London Mayor Sadiq Khan, adding that England had learned the hard way to deal with concert threats after a bomb detonated at a 2017 Ariana Grande concert killed 22 people.

Swift hasn’t yet commented publicly about the cancellations or terror threat.
