Info: found on internet, sheesh ages ago, when I was studying differences between Australian and US orders available to police in the solving of crimes.
Prior to the filing of a formal criminal charge against a person, an order authorizing the temporary detention of that person and compelling that person to submit to non-testimonial identification procedures for the purpose of obtaining evidence of that person's physical characteristics may be issued by a judge of the Superior Court pursuant to this Rule, on an application authorized in writing by the Attorney General or the Attorney General's designee or by the County Prosecutor or designated Assistant Prosecutor.
Grounds for Issuance
An order for investigative detention shall be issued only if the judge concludes from the application that a crime has been committed and is under active investigation and there is a reasonable and well-grounded basis from which to believe that the person sought may have committed the crime, the results of the physical characteristics obtained during the detention will significantly advance the investigation and determine whether or not the individual probably committed the crime, and the physical characteristics sought cannot otherwise practicably be obtained.
"Evidence of physical characteristics" shall include fingerprints, palm prints, footprints, physical measurements, handwriting and handprinting samples, blood samples, urine samples, saliva samples, fingernail scrapings, hair samples, photographs, voice exemplars, display of designated portions of the body, the taking of photographs, and appearance in a lineup.
