NEW YORK (Reuters) - Thousands of protesters stormed the security perimeter of Barclays Center in New York as protests spread across the United States over the killing of George Floyd, a Minneapolis black man who died after being pinned by the neck under a white police officer's knee.

Police made scores of arrests at Friday's massive demonstration in Brooklyn, loading cuffed protesters onto city buses lined up on Atlantic Avenue, shutting down a major thoroughfare.
