Taylor Swift is celebrating her Eras Tour staff as they approach the end of her world tour.

On Monday, Aug. 12, Swift, 34, was spotted at Annabel’s in London for the get-together, marking her first public appearance since her shows were canceled in Vienna, Austria due to an alleged planned terrorist attack.

On Aug. 7, the concert promoter, Barracuda Music, announced the cancellation in a statement and wrote they had “no choice but to cancel” the three performances at Ernst Happel Stadium in order to prioritize the safety of all attendees.

“The suspects had very specific and detailed plans to cause a tragedy on the scale of Paris, Manchester or Moscow,” Karl Nehammer, the chancellor of Austria, said at a news conference on Aug. 8, The New York Times reported.

According to authorities, who confirmed the planned attack, the suspects intended to use explosives and knives to cause mass casualties.

Since then, three suspects have been arrested. The primary suspect is a 19-year-old Austrian who admitted to planning the attack, intending to kill himself and many others at the concert, according to NBC.

The second suspect is a 17-year-old who worked at a facility management company “providing services” to the stadium. A 15-year-old boy was also detained on Aug. 7 — though he’s since been released and is being treated as a witness. Authorities determined he was not a part of the plot but knew details and corroborated crucial information. A third suspect who is believed to be connected to the main suspect was arrested on Aug. 9.

Swift has not spoken out about the situation. However, in 2019, she opened up to ELLE about her fear of violence and terrorist attacks at concerts.

“I was completely terrified to go on tour this time because I didn’t know how we were going to keep 3 million fans safe over seven months,” she said at the time.

Still, fans gathered on the streets of Vienna and sang along to her hits while trading bracelets. Swift and Disney+ also surprised fans by airing her Eras Tour film as a free TV premiere in Austria on Aug. 10 on cable station ORF. In addition, the streamer is offering a limited-time, free seven-day trial of Disney+ Premium for those fans who want to stream the movie there beginning on Aug. 10.

Up next, the “I Can Do It with a Broken Heart” singer will perform at London’s Wembley Stadium for five nights starting on Aug. 15. The Metropolitan Police Service has assured fans they are taking precautions.

“There’s nothing to indicate that the matters being investigated by the Austrian authorities will have an impact on upcoming events here in London,” police said in a statement obtained by PEOPLE.

Officials added that they work closely with venue security teams and “other partners” to guarantee proper safety protocols are in place. “As always, we will continue to keep any new information under careful review.”
