Section 365(d) in Police Regulations, Bengal , 1943
(d)Dafadars and chaukidars are permitted to make use of Government and Railway telegraphs without prepayment for all messages which relate to their police duties. These messages are of two kinds, viz., (i) ordinary telegrams, and (ii) special police telegrams. Special police telegrams shall be sent only in cases of real emergency, but when it is necessary to send a telegram during the hours when a telegraph office is closed, a special police message shall invariably be sent. In such a case, the dafadar or chaukidar shall get his message marked "Special Police," and the telegraph official is bound to accept it at any hour of the day or night. All telegrams shall be marked "State," and when an express message is sent, the words "Special Police," shall be endorsed upon it.
