A bench warrant issued under section 3505 or 3506 of this title shall be in such form as the judge prescribes and shall be signed by the clerk, and, if it is issued because of the defendant's failure to appear for judgment, shall state generally the crime of which he was convicted. A bench warrant issued under either of such sections shall be directed to any peace officer as defined in section 3561 of this title, and shall be executed by such officer in the same manner as a warrant of arrest.
