PER CURIAM.
The search which resulted in obtaining evidence introduced at the trial over objection was incidental to an arrest for violation of the narcotic laws. This arrest was made on probable cause and, therefore, was valid. We need not pass upon whether or not the search and the seizure of this evidence were valid as incidental to an arrest also made in connection with an attachment to compel appellant’s attendance as a witness at a trial then pending in the District Court. Finding no error in connection with the admission of the evidence referred to, or in other respects affecting substantial rights, the judgment of conviction is
Affirmed.
