Known depredator
（重定向自Depredator）
Known depredator (K.D.) is a term the Indian police use to classify criminals. A known depredator is a petty criminal who commits crimes such as robbery or housebreaking. Every police station maintains a list of known depredators (more commonly known as a KD list) as part of the station diary.
