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.

No one involved with the production was aware of the individual’s intent,” the N.F.L. said in a statement about the protest during Kendrick Lamar’s show.

The protester who waved a flag expressing solidarity with Palestinians in Gaza and Sudanese people during Kendrick Lamar’s Super Bowl halftime show on Sunday has been released without charges after police detained him but could not determine any charges to press against him.
