Less than an hour before doors opened for Travis Scott’s show in Tulsa, Oklahoma last night, the venue notified fans that the show would be postponed, causing havoc.

The show was slated to begin at 8 p.m. Monday night at the BOK Center. Around 6 p.m., the venue announced that the sold-out show would be postponed to March 26 due to “technical production issues.”

Fans, who were already lined up outside the BOK Center, began to show their frustration. According to Sgt. Brandon Smith, fans began to bang on the glass doors at BOK’s southeast entrance, breaking one of them. He said that police began to deploy pepper balls to disperse the crowd, but no one was struck and no injuries were reported.

The would-be concertgoers expressed their agitation online, many requesting refunds.

Scott had just performed at the Grammys Sunday night and at the Super Bowl LIII Halftime Show last weekend. Currently, he is touring in support of his 2018 record Astroworld and his Wish You Were Here Tour will run throughout late March in the U.S. Along the way, he will make appearances at Boston Calling and Rolling Loud Festival.
