(1) When a fraud or an embezzlement is detected or may reasonably be inferred from any suspicious circumstances, or there is very strong evidence to raise suspicion thereof, or where any serious irregularity is noticed in the accounts, the auditor shall forthwith report confidentially the circumstances in writing to the Chairman in the case of Municipalities and District Boards or Head of the Office in the case of other local authorities concerned and also to the Examiner.
(2) When a fraud or embezzlement has been fully investigated by the auditor, he shall submit a complete report on the case to the Examiner, who shall send copies thereof either to the Controlling Authority or the State Government, as the case may be;
Provided however, that where the Chairman or the head of the office of a local authority is involved or there are grounds for suspecting his complicity in the fraud or embezzlement or the serious irregularities, neither the preliminary nor the complete report shall be sent to any of these officers last mentioned.
