The necklaces featured a large crystal set on a gray leather string, with some featuring colorful circle pendants and others showcasing clear blue stones.

A video on TikTok showed hundreds of fans lining up at a store to claim their gift.

However, a day later, the Vienna Tourist Board revealed that due to overwhelming demand, the store had run out of the necklaces.

The 34-year-old hitmaker has not made any public statements since the alleged plot was uncovered. The arrest of a third suspect was announced on Friday.

The teen, like the two others arrested earlier, was reportedly radicalized by the Afghanistan-based ISIS-K.

Police say the main suspect, a 19-year-old man, planned to attack the tens of thousands of Swifties who gathered outside the Ernst Happel Stadium, with knives and machetes.

The suspect allegedly put together explosives as well in order to ‘kill as many people as possible,’ officials said.

The group is considered the greatest external terrorist threat to the continent, claimed UN undersecretary for counterterrorism Vladimir Vorokov, who said the group had increased its recruitment efforts on the continent.

‘When Swifties take over your street,’ wrote a fan on TikTok, showing some of the celebrations.
