Last night, pop-country stars the Band Perry were scheduled to play a sold-out show in Shelbyville, Delaware. They never made it to the stage. Instead, at the last minute, police postponed the show because of “threatening comments” from two men, as Delaware Online reports.

Police haven’t revealed what the two men said, but they were “specific to the concert.” Apparently, it was disturbing enough that everyone involved felt that shutting down the show was the best decision. They made the statement to a venue employee around 3PM, a few hours before the band was scheduled to go onstage. Police have released surveillance photos of the two men, and the show has been rescheduled for August.

The band put this statement up on Twitter:

After the recent Orlando shootings, don’t be surprised if we see this kind of thing more often. Nobody can afford to take any sort of threat lightly.

UPDATE: TMZ reports that one of the suspects arrested was Dzmitry Papou. The only information about him so far is that he has a private pilot’s license and was once took an anger management course.
