What follows is an opinion from a United States Court of Appeals. Your task is to identify the forum that heard this case immediately before the case came to the court of appeals.

PER CURIAM.
Jointly indicted for robbery and found guilty by a jury, Maynard W. Scott and Walter B. Fagan appeal. Their principal ground is that the District Court erred in refusing to suppress for use as evidence substantial sums of money found on their persons when they were arrested two or three hours after the robbery. We think the search and seizure were incidents of a lawful arrest.
We have examined all other reasons for reversal advanced by appellants but regard them as insubstantial.
Affirmed.
