(C) Effecting an arrest.
(1) Consistent with the jurisdictional limits set forth in these
regulations and with the policies of the law enforcement officer’s law
enforcement unit, where exigent circumstances prevent a law enforcement
officer from obtaining a warrant, a law enforcement officer may effect an
arrest without a warrant based on—
(a) the commission of any crime that violates federal law committed in the
law enforcement officer’s presence while the law enforcement officer is on
duty, or
(b) the commission of any felony that violates federal law if the felony
was committed or is being committed on any lands or within a facility owned
or leased by any entity within the Federal Reserve provided that the law
enforcement officer has a reasonable belief that the person to be arrested
has committed or is committing such a felony.
(2) A law enforcement officer may effect an arrest while on duty when the
law enforcement officer has knowledge of an outstanding arrest warrant
against the subject.
(3) A case report shall be completed in all situations in which a law
enforcement officer makes an arrest and shall become an official document of
any investigation. The report shall be filed with the responsible law
enforcement manager, responsible internal oversight committee (as defined
below) and with the external oversight function (as defined
below).
