Section 389(b) in Police Regulations, Bengal , 1943
(b)Each slip shall bear a serial number according to the date of issue and shall be entered in red ink in the register of letters received or despatched, as the case may be ; if the enquiry relate to an absconder, the nature of the crime with which he is charged shall be clearly noted. On receiving an enquiry slip back with the reply, it shall be pasted on the foil from which it was originally torn. Officers receiving enquiry slips shall treat them as urgent, and deal with them with the greatest possible despatch. If the slip is not received back quickly, a reminder should be issued, but if in the case of a slip sent out of the province any subsequent reminder is necessary, the officer-in-charge shall at once bring it to the notice of his Superintendent with a request to communicate with the Superintendent of the province concerned for early return of the slip.
