Taylor Swift Fans Issued Safety Advice as London Concerts Begin [Video]

Taylor Swift’s fans should be vigilant about falling victim to criminal activity as the pop star’s Eras Tour returns to London, an expert advises.

In the lead-up to Swift’s London shows, the city’s police said that a foiled attack on Vienna that might have targeted the star’s concerts there should have “no impact” on the singer’s tour dates in the U.K. capital.

Event organizers canceled three shows Swift was set to hold at Vienna’s Ernst Happel Stadium last week as part of her tour, following the arrest of two people in Austria. Authorities said the two suspects were planning attacks inspired by the Islamic State militant group (ISIS). A third person was arrested shortly afterward.

Swift is scheduled to play five dates at London’s Wembley Stadium, from Thursday to August 20. Around 450,000 attendees are expected to attend the sold-out shows, which are occurring not long after the Vienna plot made headlines.
