This is an appeal from judgment of conviction for robbery. The primary issue raised relates to the refusal of the District Court to instruct the jury that a written statement introduced in the process of impeaching a government witness, whose testimony had surprised the prosecution, was to be considered only on the issue of credibility. The factual situation presented by this ease is unlike the usual impeachment of “turncoat” witnesses under D.C. Code Ann. § 14-104 (1961), such as we dealt with in Bartley v. United States, 115 U.S.App.D.C. 316, 319 F.2d 717. See Wheeler v. United States, 93 U.S.App.D.C. 159, 211 F.2d 19 (1953). In this case the “turncoat” witness, when cross-examined by the prosecutor, recanted his original testimony which had taken the government by surprise, acknowledged the truth of his prior out of court statement and adopted that as his testimony. See Robinson v. United States, 113 U.S.App.D.C. 372 at 377, 308 F.2d 327 at 332 (1962). In light of these events, the receipt of the statement, even if assumed, arguendo, to be error, was harmless since it said no more than what the witness had said from the stand.

We have examined the record in light of other contentions and find ample evidence to support the verdict.

The judgment of the District Court is therefore

Affirmed.
