Police officers requiring funds for police investigative work shall make a request for moneys from the police investigative revolving fund to the custodian of the fund upon forms to be provided, which shall indicate the purpose of the request, the anticipated cost and the police officers assigned to the investigation. The chief of police shall establish a time, not less than thirty days, after the moneys have been disbursed from the fund to require the police officers to whom the moneys were disbursed to present a voucher indicating the amount expended, the purpose for which expended and the amount unexpended, together with a statement by such officer that such expenditure was made in connection with necessary investigations of criminal activity within the City. The unexpended portion, unless needed for a continuing investigation, shall accompany the voucher. No part of any moneys disbursed for police investigative purposes shall be considered as a personal loan to such police officer and any expenditure thereof, other than for official police business purposes, shall be considered a misappropriation of public funds. It is not intended that the funds shall be used for any purpose other than police investigative work and reimbursable expenses incurred shall be separately paid by an appropriate expense voucher as in other cases. (Ord. 685 § 18, 1975).
