REVERSED. Under the circumstances of this case, it is our view that the trial court erred in refusing to allow the appellant to establish on cross-examination that one of the prosecution’s principal witnesses was on probation. See Davis v. Alaska, 415 *486U.S. 308, 94 S.Ct. 1105, 39 L.Ed.2d 347 (1974). Accordingly, this cause is reversed for a new trial.
