SCOTT, Justice.
Defendant was found guilty by a district court jury of introducing contraband into prison, Minn.Stat. § 243.55 (1978). The trial court stayed imposition of sentence and placed defendant on five years probation, with 45 days in jail under the Huber law. The trial court stayed execution of the probationary jail term pending this appeal from judgment of conviction. Defendant contends that her conviction should be reversed outright on one of two grounds: insufficiency of evidence and failure of the state to comply with the discovery rules. With respect to the latter ground she argues alternatively for a new trial.
We reverse and remand for a new trial.
Without summarizing the evidence in detail,1 we believe that the evidence was sufficient to sustain defendant’s conviction, and, but for the issue of the failure of the state to comply with the discovery rules, we would affirm defendant’s conviction.
The basic facts relating to the discovery issue are as follows:
(a) At the omnibus hearing Officer William Arendt, a guard who observed the incident which led to defendant’s arrest and the search of her person, testified, in response to questions by defense counsel, that he and other guards felt “that there would be drugs being smuggled in” on the day in question but he denied having any information, specific or general, that defendant would try to smuggle in drugs.
(b) Then at trial, apparently assuming that he would get the same answer, defense counsel asked both Officer Arendt and Sergeant Michael Hermerding on cross-examination if they had had any information giving them reason to suspect that defendant would attempt to smuggle drugs in on the day in question. Hermerding testified that two reliable informants had told them that defendant would be smuggling in drugs, and Arendt testified that he had had specific information from one prisoner that defendant would attempt to smuggle in drugs.
(c) Defense counsel then confronted Ar-endt with his prior inconsistent testimony at the omnibus hearing, and he replied that he was not saying that that testimony was wrong. On redirect Arendt testified that he had testified as he did at the omnibus hearing in order to protect the informer,
