Thousands of anti-police brutality protesters marched across the Brooklyn Bridge on Thursday, following a memorial for George Floyd — the black Minneapolis man whose death at the hands of a white cop has sparked nationwide outrage.

The massive crowd made the trek from Cadman Plaza in Brooklyn, over the bridge and to Foley Square in Lower Manhattan, erupting into chants of “Say his name: George Floyd” and “No justice. No peace.”

They stopped at various intervals, taking a knee and joining in call and response chants, as police officers tried to keep them moving.

Among the marchers was Floyd’s brother, Terrence Floyd, who made a peace sign as he was driven in a car alongside the group, wearing a Yankees hat and a face mask printed with a picture of his late sibling.

Earlier in the day, Terrence, a Brooklyn resident, spoke to a 5,000-person group gathered at Cadman Plaza to mark the life and death of his brother.

He was hailed with cheers as he thanked the crowd for their protests and urged they remain peaceful.

“I’m proud of the protest, but I’m not proud of the destruction,” he said. “My brother wasn’t about that. The Floyds is a God-fearing family.”

A roster of local pols also addressed the crowd, including Mayor de Blasio, who rushed off the stage after five minutes, following intense booing and jeering from the attendees.
