During the course of the prosecutor’s direct examination of the agent who had made the arrests, he inquired as to the agent’s prior knowledge concerning the automobile in which the unstamped whiskey had been found. Over defense counsel’s objection, the court allowed testimony that the agent had been told by a confidential informer that the same car, identified by color and by its license number, had been used to transport illicit whiskey and sugar between Tallahassee, Florida, and Walton County, Florida. The testimony was as follows:
“Q Now then, this automobile, did you know anything about this particular automobile prior to that time ?
MR. TONEY: Objection; I’m anticipating, Your Honor.
MR. CARROUTH: What is the objection?
THE COURT: He’s anticipating an answer about information, I suppose.
MR. CARROUTH: That’s what I intend to develop.
THE COURT: I overrule the objection at this point.
Q Mr. Carrouth: Go ahead. Did you have any knowledge of that particular automobile prior to this time?
A Yes sir. As I approached the dwelling house—
MR. TONEY: Objection. The answer yes or no would be responsive, Your Honor please.
Q Mr. Carrouth: And if you did have any information about this car, state what you had ?
MR. TONEY: Objection; hearsay.
THE COURT: I overrule the objection.
Q Mr. Carrouth: Go ahead, Mr. Hardman?
A Yes sir, I had had previous information concerning the car; and, as I approached the dwelling house for the original interview, I recognized the car as the one that I had previously, had previously been described to me on November 26, 1964. I had received information from a confidential informer, who had previously—
MR. TONEY: Objection, Your Honor. This is the same type of objection, I realize, but I want to make it clear in the record.
THE COURT: I overrule the objection.
A The Witness: — who had previously proved reliable to me, that a blue-green 1964 Galaxy Ford, license No. 13-W-6942, was being used to transport illicit whiskey and sugar between Tallahassee, Florida, and Walton County, Florida.”
Thereupon a defense motion for a mistrial was overruled; but the trial judge subsequently found the testimony to have been improperly admitted, and instructed the jury at length to disregard the agent’s statement as to what some other person had told him.
Appellants contend that the damage was done, that they had been unduly prejudiced in the eyes of the jury by this admittedly irrelevant, hearsay evidence. We agree. In our recent decision in Landsdown v. United States, 348 F.2d 405 (5 Cir. 1965), we held that where law enforcement personnel testified that they had received a radio call in connection with attempts to sell some jewelry by two suspects, one of which was the appellant there, and that a burglary complaint had come in over the telephone, such testimony was irrelevant to the case, inadmissible as hearsay, and so unduly prejudicial as to constitute plain error under Fed.R.Crim.P. 52(b).
Perhaps more nearly in point is Mattson v. United States, 7 F.2d 427 (8 Cir. 1925), where a conviction for violation of the Prohibition laws was reversed because the agent had asserted that he had had many complaints that the defendant was selling liquor. It was held that the agent’s statement was “clearly inadmissible and fatally prejudicial to the case of the defendant, because it was bald hearsay, or hearsay of hearsay.” See also Whiting v. United States, 296 F.2d 512 (1 Cir. 1961).
