Minn. Stat. § 629.32: MINIMUM RESTRAINT ALLOWED FOR ARREST; WARRANT SHOWN UPON REQUEST.

A peace officer making an arrest may not subject the person arrested to any more restraint than is necessary for the arrest and detention. The peace officer shall inform the defendant that the officer is acting under a warrant, and shall show the defendant the warrant if requested to do so. An arrest by a peace officer acting under a warrant is lawful even though the officer does not have the warrant in hand at the time of the arrest, but if the arrested person so requests the warrant must be shown to that person as soon as possible and practicable. A peace officer may lawfully arrest a person when advised by any other peace officer in the state that a warrant has been issued for that person.
