Colinford Mattis, a lawyer accused of helping throw a Molotov cocktail at an unoccupied New York City Police Department vehicle in Brooklyn during protests against police brutality, pleaded not guilty to a seven-count indictment during a short arraignment Wednesday.

Because of the coronavirus pandemic, the hearing for Mattis was held by conference call, which was briefly interrupted by enthusiastic supporters.

"Love you, Colin," one voice called out as the hearing began.
