Arthur Gilchrist was indicted on three counts, one for possessing a letter (a federal tax refund check) known to have been stolen from the mails, and the other two for having forged and uttered a United States Treasurer’s check. After a jury trial, he was convicted on all counts. He now appeals pro se attacking the sufficiency of the evidence and claiming that his arrest was unlawful, that he received no preliminary hearing, and that the indictment was insufficiently informative as to the crimes charged.

The Government’s case rested largely on the testimony of Gilchrist’s accomplice, Dorothy Bertrán, with whom he had arranged identification papers and who actually presented the forged check for cashing. Her testimony was sufficient, if believed, to establish Gilchrist’s guilt on all three counts- — his possession of the stolen check and his aiding and abetting her in its forging and uttering. Most of Gilchrist’s points on appeal are merely arguments directed to possible inconsistencies in the Bertrán testimony, some based on extra-record informatio^___ which go to her credibility.

The illegal arrest claim has not been made before and is not open now. The same principle applies to appellant’s claim that he was not afforded a preliminary hearing which, in any event, was no longer required once the indictment was returned. Moreover, the alleged illegality would call only for exclusion of evidence seized or — on some occasions — • of oral statements made, of which there were none.

*716 As for the indictment, it charged in the statutory language with sufficient clarity and reference to the precise letter and check in question. That is sufficient.

Affirmed.
