The scene outside a Travis Scott concert turned into mayhem after the performance was postponed shortly before the rapper was supposed to take the stage.
Fuming fans in Tulsa, Okla., chanted "Let us in!" and some even rushed toward the doors at the BOK Center after realizing one was open following Monday night's postponement, video shared to social media shows.
One fan got pepper sprayed amid the madness, local news station KTRK reported.
"Due to technical production issues, tonight's sold out Travis Scott show in Tulsa will be moved to March 26th," the BOK Center tweeted Monday at 6:10 p.m. local time. "All tickets purchased for tonight's show will be honored at the rescheduled show on March 26th."
Footage of the scene outside the arena shows one fan hurling a water bottle at a glass door, appearing to leave a crack.
Police standing inside the venue sprinted outside, meanwhile, after a fan opened one of the doors.
"Tulsa so sorry I can't perform at tonight's sold out show," Scott tweeted a little over an hour after the venue tweeted the cancellation news. "We had last minute production issues and I can't give y'all an incomplete show. Rescheduled to March 26 all tix still valid. Everyone get home safe."
No one was believed to be injured during the chaos.
The 26-year-old Scott, who is in the midst of his "Astrowold-Wish You Were Here Tour 2," is scheduled to perform in his hometown of Houston on Tuesday night.
The rapper, whose hits include "Sicko Mode" and "Goosebumps," performed during the Super Bowl halftime show last week before taking the Grammys stage Sunday.
