The department said Monday that 14 vehicles were a total loss because of fire damage, seven are still being repaired and the rest have returned to service.
Several people were arrested in the early days of the unrest for allegedly hurling Molotov cocktails at police vehicles in Brooklyn. Those cases are still pending in federal court.
In the latest incident, Saturday night in Manhattan, a man was seen on video using a protest sign to bash the window of a parked police van while another man sprayed graffiti onto an adjacent police van.
