Hard drives containing some of Beyoncé's unreleased music, footage plans for future shows, and set lists have been stolen from the car of her choreographer, Christopher Grant, in Atlanta.

They lost more than just clothing, sunglasses and headphones. According to an Atlanta police report, the thief also made off with thumb drives containing the singer's “unreleased music.” Police say they have identified a suspect, but they hadn't announced any arrests as of Tuesday.

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. The police said a suspect had emerged.
