Holding

Where there was no probable cause to arrest petitioner, no consent to the journey to the police station, and no prior judicial authorization for detaining him, the investigative detention at the station for fingerprinting purposes violated petitioner's rights under the Fourth Amendment, as made applicable to the States by the Fourteenth; hence the fingerprints taken were the inadmissible fruits of an illegal detention.
