Boston police said a group of between 200 to 300 protesters blocked Tremont Street near Winter Street around 6:46 p.m., while officers were responding to an unrelated emergency three blocks away.

“When officers attempted to move the group to the sidewalk to allow emergency vehicles to pass, protesters surrounded police cruisers, kicked vehicle doors, and resisted dispersal efforts,” the department said in a statement.
