Cardi B won’t be performing in Indianapolis Tuesday (July 30), as planned. The show was canceled at the last minute over a “security threat and safety concerns,” the venue announced in a statement.

“Due to a security threat and safety concerns at this evening’s show, management has advised that this show be postponed,” reads a statement from Bankers Life Fieldhouse. The venue also assured the public that the threats are “under investigation.”

The cancellation came minutes before Cardi was set to take the stage and fans were understandably disappointed and upset about the news. According to The Blast, a threat was made against the 26-year-old rapper’s safety.

The “Money” rapper was at the venue rehearsing “a new move” when she learned of the security threat. “My safety and your safety [comes] first,” Cardi wrote in an apology tweet to fans. The performance has been rescheduled for Sept. 11.
