NEW ORLEANS — A performer who was part of Kendrick Lamar’s Super Bowl halftime show was detained by security after waving the Sudanese flag and Palestinian flag together with the words “Sudan” and “Gaza” written on them toward the end of the performance, the NFL said.

“Peekaboo,” a post on Good Dye Young’s Instagram account reads, “GDY Spotted on the Super Bowl Halftime Stage @kendricklamar & @sza Dancers’ showed up and showed outtt with Good Dye Young custom split dye by @luckylettty.” In the replies, Williams wrote, “Screaming at my TV!”
