Two members of Beyoncé’s team said that their S.U.V. was broken into on July 8, just before a series of concerts in Atlanta, the authorities said.

Thumb drives containing Beyoncé’s unreleased music, future set lists and more have been stolen from her lead choreographer and one of her dancers, according to the Atlanta Police Department.

The theft of the materials, stored on five thumb drives, happened on July 8, two days before Beyoncé began a four-day residency at Atlanta’s Mercedes-Benz Stadium.
