An investigative arrest warrant shall mean a warrant for the arrest of a person charged with a criminal offense as distinguished from a bench warrant for failure to appear or to pay a fine.
The investigating law enforcement agency shall exercise this opportunity by advising the repository that it wishes to take physical possession of the attested warrant for the 72-hour period. A representative of the investigating law enforcement agency shall sign an appropriate receipt for the attested warrant, if required by the repository. It shall be the responsibility of the law enforcement agency to return the attested warrant to the warrant repository at the end of the 72-hour period, except in those cases governed by paragraph (D) below.
The Attorney General, the respective District Attorney or their designees shall exercise this authority by advising the repository that the primary investigative law enforcement agency shall take physical possession of the attested warrant for an initial period not to exceed five days. At the expiration of the initial five-day period, the Attorney General, the respective District Attorney or their designees may authorize the primary investigating law enforcement agency permission to physically possess the attested warrant for an additional period not to exceed five days if the likelihood of execution will be increased. The repository shall maintain a record of the officer authorizing physical possession under this paragraph.
In the event the primary investigating law enforcement agency has possessed the attested warrant for the 72-hour period under paragraph (C) above, the five-day periods under this paragraph shall be calculated from the expiration of the 72-hour period. Otherwise, the five-day periods shall be calculated from the day of delivery of the attested warrant to the repository and the day of delivery shall not be counted. In no event, however, shall the primary investigating law enforcement agency physically possess the attested warrant for more than a total of thirteen days from the day of its receipt at the repository.
It shall be the responsibility of the primary investigating law enforcement agency possessing an attested warrant under this paragraph to return the warrant to the designated repository at the end of the authorized possession period.
