PER CURIAM.
Defendant was found guilty of unarmed robbery (MCLA 750.530; MSA 28.798) by a judge in Detroit Recorder's Court sitting without a jury. Defendant raises several issues on appeal which we need not consider in view of our disposition of the case. The record reveals that five days before defendant's trial on the instant charge, defendant's guilty plea to another charge was accepted and he was sentenced to a term in prison by the same judge who convicted and sentenced defendant on this charge. At that time the court had occasion to study a presentence report regarding the defendant. We believe that the judge's recent study of the presentence report brings this case within the holding of People v. Frazier Walker, 24 Mich. App. 360, 362 (1970) (aff'd 385 Mich. 596), wherein this Court stated:
"We are satisfied that had a jury voir dire examination disclosed that any prospective jurror [sic] possessed the information that the trial judge possessed prior to trial, that juror would have been excused by the trial judge for cause. Similarly, we challenge the trial judge for cause as trier of the fact and excuse her. A judge, the same as a juror, does not pass the required test of impartiality once possessed of the type of information this record discloses that the trial judge possessed prior to trial."
Reversed and remanded.
