STOCKHOLM (AP) — U2 has canceled a concert in Sweden after a security breach prompted police to evacuate the Globe Arena in Stockholm.

Police said they stopped the event late Sunday due to a security problem as spectators entered the arena.

They didn't specify the reason but said they had started an investigation regarding a possible weapons violation. No suspect was arrested.

In a statement on U2's home page, the organizers said the show was rescheduled for Tuesday. They apologized for the inconvenience and said the audience's "safety is the priority."
