(1) Warrants. If it appears from the complaint, or from an affidavit or affidavits filed with the complaint or after an examination under oath of the complainant or witnesses, when the judge determines that this is necessary, that there is probable cause to believe that an offense has been committed and that the accused has committed it, the judge shall issue a warrant for the arrest of the defendant or a summons in lieu thereof. The warrant or summons shall be delivered forthwith to a law enforcement officer for service. (a) When an accused has been arrested without a warrant and is in custody or appears voluntarily before a judge, no warrant shall be issued and the complaint shall be filed forthwith with a judge. (b) A warrant or summons may be issued by a judge in another county when there is no available judge of the county in which the complaint is issued. The warrant shall be returnable before a judge in the county in which the offense alleged in the complaint was committed, and the summons shall be returnable before the circuit court of the county in which the offense alleged in the complaint was committed. (c) A judge may specify geographical limits for enforcement of a warrant. (d) An examination of the complainant or witness under sub. (1) may take place by telephone on request of the person seeking the warrant or summons unless good cause to the contrary appears. The judge shall place each complainant or witness under oath and arrange for all sworn testimony to be recorded, either by a court reporter or by means of a voice recording device. The judge shall have the record transcribed. The transcript, certified as accurate by the judge or reporter, as appropriate, shall be filed with the court. If the testimony was recorded by means of a voice recording device, the judge shall also file the original recording with the court. (2) Summons. (a) In any case the district attorney, after the issuance of a complaint, may issue a summons in lieu of requesting the issuance of a warrant. The complaint shall then be filed with the clerk. (b) In misdemeanor actions where the maximum imprisonment does not exceed 6 months, the judge shall issue a summons instead of a warrant unless the judge believes that the defendant will not appear in response to a summons. (c) If a person summoned fails to appear in response to a summons issued by a district attorney, the district attorney may proceed to file the complaint as provided in s. 968.02 and, in addition to endorsing his or her approval on the complaint, shall endorse upon the complaint the fact that the accused failed to respond to a summons.

(b) A warrant is served by arresting the defendant and informing the defendant as soon as practicable of the nature of the crime with which the defendant is charged. (c) An arrest may be made by a law enforcement officer without a warrant in the law enforcement officer’s possession when the law enforcement officer has knowledge that a warrant has been issued.
