Wong Sun v. United States, 371 U.S. 471 (1963)
In a trial in a Federal District Court without a jury, petitioners were convicted of fraudulent and knowing transportation and concealment of illegally imported heroin, in violation of 21 U.S.C. §174. Although the Court of Appeals held that the arrests of both petitioners without warrants were illegal, because not based on “probable cause” within the meaning of the Fourth Amendment nor “reasonable grounds” within the meaning of the Narcotics Control Act of 1956, it affirmed their convictions, notwithstanding the admission in evidence over their timely objections of (1) statements made orally by petitioner Toy in his bedroom at the time of his arrest; (2) heroin surrendered to the agents by a third party as a result of those statements; and (3) unsigned statements made by each petitioner several days after his arrest, and after being lawfully arraigned and released on his own recognizance. The Court of Appeals held that these items were not the fruits of the illegal arrests, and, therefore, were properly admitted in evidence.
1. On the record in this case, there was neither reasonable grounds nor probable cause for Toy’s arrest, since the information upon which it was based was too vague and came from too untested a source to accept it as probable cause for the issuance of an arrest warrant; and this defect was not cured by the fact that Toy fled when a supposed customer at his door early in the morning revealed that he was a narcotics agent. Pp. 371 U. S. 479-484.
2. On the record in this case, the statements made by Toy in his bedroom at the time of his unlawful arrest were the fruits of the agents’ unlawful action, and they should have been excluded from evidence. Pp. 371 U. S. 484-487.
3. The narcotics taken from a third party as a result of statements made by Toy at the time of his arrest were likewise fruits of the unlawful arrest, and they should not have been admitted as evidence against Toy. Pp. 371 U. S. 487-488.

4. After exclusion of the foregoing items of improperly admitted evidence, the only proofs remaining to sustain Toy’s conviction are his and his codefendant’s unsigned statements; any admissions of guilt in Toy’s statement require corroboration; no reference to Toy in his codefendant’s statement constitutes admissible evidence corroborating any admission by Toy, and Toy’s conviction must be set aside for lack of competent evidence to support it. Pp. 371 U. S. 488-491.
5. In view of the fact that, after his unlawful arrest, petitioner Wong Sun had been lawfully arraigned and released on his own recognizance and had returned voluntarily several days later when he made his unsigned statement, the connection between his unlawful arrest and the making of that statement was so attenuated that the unsigned statement was not the fruit of the unlawful arrest and, therefore, it was properly admitted in evidence. P. 371 U. S. 491.
6. The seizure of the narcotics admitted in evidence invaded no right of privacy of person or premises which would entitle Wong Sun to object to its use at his trial. Pp. 371 U. S. 491-492.
7. Any references to Wong Sun in his codefendant’s statement were incompetent to corroborate Wong Sun’s admissions, and Wong Sun is entitled to a new trial, because it is not clear from the record whether or not the trial court relied upon his codefendant’s statement as a source of corroboration of Wong Sun’s confession. Pp. 371 U. S. 492-493.
