BUFFALO, N.Y. (WIVB) — Police have taken a man who was seen throwing a burning box through a broken window at city hall into custody.

A vow by Buffalo Mayor Byron Brown came just about two hours after violent clashes with police and vandalism spiked on Niagara Square.

“We have you on camera, you idiot. We are going to find you and prosecute you to the fullest extent of the law. So get ready, because we’re coming,” Brown said.

News 4 photographer Dan Holland caught the shirtless man on camera walking toward a pile of burning debris.

He picks up what appears to be a burning box and walks toward a broken first-floor window. As the shot widens, the man is seen jumping from the window. He walks toward us, examining what, no doubt, are burns on his arms.
