British police said Thursday there was nothing to indicate that a planned attack on a Taylor Swift concert in Vienna would have an impact on her shows at Wembley Stadium, London, next week. Swift's three concerts in Vienna, expected to draw 195,000 people, this week were cancelled after the threat was discovered. "There is nothing to indicate that the matters being investigated by the Austrian authorities will have an impact on upcoming events here in London," a spokesperson for London's Metropolitan Police said. She will perform at Wembley on August 15 for five nights before heading back to North America for her final tour dates. Austrian police on Wednesday detained two people suspected of plotting attacks on concerts. One of them, a 19 year-old suspect, had a particular focus on the Swift concerts in Vienna, they said.
