In England since the Metropolitan Police Services inception in 1829, officers have been issued with the "Metropolitan" whistle. Prior to this, police used hand rattles, with whistles only being used as musical instruments or toys. Both rattles and whistles were used to call for back-up in areas where neighbourhood beats overlapped, and following their success in London, the whistle was adopted by most counties in England.
