Security personnel evacuated the Kennedy Center Thursday morning after a bomb threat targeting Shen Yun performances, a Kennedy Center spokesperson said.

A police spokesperson told the Washington Post that D.C. police received a call reporting a bomb threat at the Kennedy Center at 10:44 a.m. The department’s Explosive Ordnance Division assisted the U.S. Park Police in responding to the threat, the spokesperson told the Post.

The Metropolitan Police Department confirmed that the Explosive Ordnance Disposal unit has since cleared the scene. No hazardous material was found, a MPD spokesperson said.

The investigation earlier shut down the Rock Creek Parkway between Virginia Ave NW and the Roosevelt Bridge. The parkway has reopened, according to WTOP Traffic.

U.S. Park Police deferred comment to the Kennedy Center.

Shen Yun is a classical Chinese dance group that has faced controversy, including a November lawsuit accusing the group of forced labor and trafficking. The group was scheduled to perform at the Kennedy Center Feb. 20 through Feb. 23, starting with a show Thursday evening at 8 p.m.

The Kennedy Center recently drew national attention after President Trump ousted several board members and had the new board install him as the center’s chair.

“Security acted swiftly, following existing protocols,” the Kennedy Center spokesperson told The Hatchet.
