After a trial by jury in the United States District Court for the Southern District of New York, McLean, J., the appellant Bracer was found to have violated 21 U.S.C. §§ 173-174 by receiving, concealing, selling, and facilitating the transportation, etc., of approximately 4 grams and 340 grams of heroin on two separate occasions on April 10, 1963, and to have conspired with co-defendants Torres and Solero to violate §§ 173-174. He received concurrent 7-year sentences on all counts. Bracer was arrested without a warrant on April 10, 1963 following the arrest on April 8 of Solero, who informed the agents that he had been obtaining his heroin from Bracer. At the time of his arrest, Bracer’s car was searched and a package of heroin discovered on the floor, and while being interrogated Bracer volunteered to the arresting agent that he had additional heroin stored in his apartment. Bracer then consented to a search of his apartment. Bracer now contends that the search of his home was without his consent and hence unlawful, that his arrest without a warrant was illegal, in that probable cause was lacking, and that the heroin obtained at the time of his arrest was hence inadmissible evidence, and that there was insufficient evidence to support the conspiracy conviction. He has failed to demonstrate error on either of the substantive counts, and we affirm the judgment on the substantive counts. We do not reach the conspiracy count.
In the first place, the arresting agent Bailey had probable cause to make the arrest and to search Bracer’s automobile. The evidence outlined below, obtained through the agents’ surveillance showed to a high degree of *524 probability that the appellant was an integral part of the distribution scheme and further served to substantiate Sol-ero’s claim that Bracer was the source. When, on April 1, Solero ventured out to obtain an additional ounce of heroin for Bailey who was acting as a purchaser, Solero was seen by the agents to proceed directly to Bracer’s apartment and to return immediately to Bailey with the additional heroin. Furthermore, the files of the narcotics bureau showed that Bracer had previously been convicted for a narcotics violation, and information Bailey had received from a fellow agent disclosed that appellant was engaged in the narcotics trade. Finally, on April 3, Solero told Bailey that he was going to meet his connection. Agents watching Solero then saw him proceed to a street corner in the Bronx where, after waiting a short while, he twice motioned to Bracer who drove past him on two different occasions without stopping; and, when Solero returned to Bailey, he told Bailey that he had just seen his connection, but that his connection for some reason did not stop.
26 U.S.C.A. § 7607 empowers a narcotics officer to make arrests without a warrant for violations of the narcotics laws when he has “reasonable grounds to believe that the person to be arrested has committed or is committing such violation.” “Reasonable grounds” is construed to mean probable cause, and probable cause is defined to mean more than mere suspicion, but not that the arresting officer be in possession of evidence sufficient to result in the conviction of the suspect — it requires evidence which would “warrant a man of reasonable caution in the belief” that a felony has been committed. Wong Sun v. United States,
Bracer next contends that the search of his home was without his consent and hence unlawful. According to the Government, after the agents arrested Bracer, they informed him that they would have to obtain a search warrant in order to search his apartment. Bracer, it was claimed, then freely consented to such a search and led two agents to his apartment where an additional supply of heroin was uncovered. At trial, appellant moved to suppress the evidence thus obtained on the ground that he had withdrawn his consent upon reaching his apartment door.
The trial court denied the motion to suppress, finding that the search was conducted by the agents with the consent and approval of Bracer. While it is true that the Government has the burden of proving by clear and positive evidence that such consent was given, Channel v. United States,
