3rd Teenager In Custody Over Foiled Plot Targeting Taylor Swift Vienna Shows

VIENNA (AP) — A third teenager has been arrested in connection with a foiled attack on now-canceled Taylor Swift concerts in Vienna, Austria’s interior minister said Friday.

Austrian Interior Minister Gerhard Karner said an 18-year-old was taken into custody Thursday evening in Vienna after allegedly being in contact with the main suspect. Karner announced the arrest during an unrelated news conference Friday.

Investigators are scrutinizing the “networks” of the suspects, the Austrian interior ministry told The Associated Press on Friday, adding in a statement that investigators have turned to evaluating physical and electronic evidence.

The 19-year-old main suspect and a 17-year-old were arrested Tuesday, while a 15-year-old was also interrogated but was not arrested. None of their names were released, in line with Austrian privacy rules.

Officials said Thursday afternoon that no additional suspects were being sought. They did not immediately offer further details Friday.

Authorities say the plot appeared to have been inspired by the Islamic State group and al-Qaida. Investigators found bomb-making materials at the main suspect’s home. Officials say that teenager has confessed to planning to “kill as many people as possible outside the concert venue” using knives or homemade explosives.

Officials say the main suspect and the 18-year-old arrested Friday both pledged “oaths of allegiance” to the Islamic State group.

The 18-year-old “comes from the social environment” of the main suspect, Karner said.

“He had been in contact with the main perpetrator, but is not directly connected to the attack plans,” the minister said. “But, as was found out a few days ago, he took an oath of allegiance specifically to the IS on Aug. 6.”
