Rascal Flatts concert ends abruptly, investigation underway

Updated statement from Live Nation about the Rascal Flatts concert:

“Last night a safety concern presented itself during the Rascal Flatts’ concert in Noblesville. Venue staff and local officials followed standard protocols to ensure the safety of guests, the artist and staff. Law enforcement agencies are investigating the matter.”

NOBLESVILLE, Ind. -- Some Rascal Flatts fans in Indiana are waking up a bit confused after they say last night's concert abruptly ended at Ruoff Home Mortgage Music Center, according to WXIN.

There are a lot of theories and questions this morning, and some of the concertgoers have been sharing what they heard and saw on Twitter and Facebook.

Some fans say there was a disturbance close to the stage; others say a fight broke out. But none of that has been confirmed by officials at this point, according to WXIN.

According to the IndyStar, one witness said the concert was nearing its end when the band stepped off the stage. That’s when the crowd went wild, hoping and expecting an encore. At that point, the band had not played some of their top songs “God Bless the Broken Road” and “Life Is a Highway.”

But the band never came back on stage.

"Everyone boo’d," Sherlock told IndyStar. "We continued to wait in the pavilion, and that’s when security came up to everyone and told us to leave. I asked what was going on and he replied, 'We were told to evacuate the pavilion immediately.' "

According to concertgoers, security started evacuating fans and an announcement was made over the PA system that said the show was over.

It’s still unclear what exactly happened. Bryant Orem, a spokesperson for the Hamilton County Sheriff’s Office, released a statement:

“I cannot comment on an open investigation but will forward information as it becomes available to me.”
