Cardi B was scheduled to play a show last night in Indianapolis, but due to an “unverified threat,” she called-off the gig last-minute.

“This evening, there was a scheduled concert at Bankers Life. We were notified of an unverified threat to the artist and the artist canceled this evening’s concert – there is no immediate threat to public safety, this is not an active incident. Ongoing investigation,” the Indianapolis Metropolitan Police Department said in a statement on Twitter.

The rapper also took to Twitter to apologize but noted that safety is her top priority. Along with her message, she shared a video that had been recorded during her rehearsal to show that she was indeed practicing before heading onstage, and this incident was very real.

“Dear Indiana people I’m so sorry for today. I will like to let you know I was at the venue I was even rehearsing a new move I been excited to do on my show,” she tweeted. “Unfortunately there was a security threat that is currently under investigation right now. My safety and your safety first.”

“I want to thank the promoters we have already rescheduled the show,” she added. “I’m so sorry guys I never dealt with a situation like this before and I’m not taking any chances. I love you guys.”

Officers reassured fans that there was “no immediate threat to public safety,” however the “unverified threat” has not been determined, and information has not been released to the public at this time.

The concert has been postponed to September 11, with all tickets honored during the new show date.

Earlier this month, Cardi B confirmed that she would not be going on a tour in support of her breakthrough debut record, Invasion of Privacy, as some fans would have hoped. In a now-deleted Instagram post, the rapper outlined how much money she makes per festival appearance, noting that she brings in a significantly larger check at a festival than she would on tour.

“Now why would I do that now when I can go on tour on my second album while I got festival and independent Cardi concerts money?” she said in the post. “Mhhhmmm.. You see ya might think I’m dumb cause my attitude or the way I think but one thing bout Bardi I loveee money and I know how to make it.”

Cardi B can be found performing at a handful of music festivals this summer and fall, making stops at the Real Street Festival in Anaheim, Made In America Festival in Philly, Texas’ Austin City Limits, and Music Midtown in Atlanta. Grab tickets to see the rapper on tour this year via Ticket Club.
