Country group Rascal Flatts abruptly ended an Indiana concert because of what police call a "security issue" that remains under investigation. Concertgoers say the band didn't return for an expected encore Thursday night at Ruoff Home Mortgage Music Center in suburban Indianapolis, after which a public-address announcement said the show was over and security guards told people to leave, per the AP. One fan tells the Indianapolis Star he saw a disruption in the general-admission area closest to the outdoor amphitheater's stage.
"Lights come on and security is pulling some guy looking to be in his 20s out of the pit," he says. "Everyone is standing around, looking at each other and wondering what is going on." The Hamilton County Sheriff's Department said Friday the matter is an open investigation, but did not release further details. Rascal Flatts said on Twitter that everyone was able to leave safely and thanked fans for their understanding. (Read more Rascal Flatts stories.)
