OPINION
This action arose out of a collision between a police squad car and a tow truck. An issue at trial was whether the squad car’s siren had been activated. The jury returned a verdict for the tow truck operator, and the district court denied appellants’ motion for new trial. Appellants contend that the district court erroneously instructed the jury that it could make an adverse inference from appellants’ failure to produce a tape that might have corroborated evidence as to the siren because (1) no evidence that has been shown to exist has been destroyed; (2) there was no finding that the tape, if it existed, was critical to respondents’ case; and (3) respondents did not suffer prejudice because they were not placed at an evidentiary disadvantage. Because the district court did not abuse its discretion, we affirm.
FACTS
This action arose out of a May 1997 collision between a police squad car and a tow truck, resulting in personal injuries and property damage. Appellant Jonathon Kingsbury, a Minneapolis police officer, was driving a squad car, accompanied by Officer Gary Nelson. Terrance Wojtow-icz was driving the tow truck, owned by respondents Larry Wajda and L & L Towing. 1 In 1999, Officer Nelson and his wife *859 brought a personal injury lawsuit against Wojtowicz and Wrecker Services for injuries sustained in the collision. Wojtowicz and Wrecker Services brought a third-party action against appellant City of Minneapolis, seeking contribution for any damages awarded to the Nelsons, and the city counterclaimed for damages to the squad car and for workers’ compensation benefits paid to Officer Nelson. L & L Towing and Wajda filed a complaint against the city and Officer Kingsbury for property damage to the tow truck, alleging negligence by Kingsbury. The district court consolidated the cases.
The city moved for summary judgment, claiming official immunity for itself and Officer Kingsbury, and the district court granted the city’s motion. This court reversed the district court’s grant of summary judgment and remanded for trial.
Nelson v. Wrecker Servs., Inc.,
At trial, a primary issue was whether the squad car’s siren had been activated. Wojtowicz testified that he was traveling eastbound on 10th Avenue toward the intersection of 10th Avenue and Washington, with the truck windows open, and that the traffic light was green as he entered the intersection. Wojtowicz stated that he noticed a car to his right, facing north, that was stopped inside the northbound lane on Washington. He noticed overhead lights when the squad car was “almost hitting” him. Wojtowicz did not hear a siren and was never cited for any traffic violations in connection with the incident.
Officer Kingsbury testified that after receiving a radio dispatch that a knife fight was taking place nearby, the officers responded to the call, activating the squad car’s red lights and siren. Kingsbury stated that he traveled northbound on Washington Avenue, and as he approached the intersection of Washington and 10th Avenues, he noticed a car stopped at the intersection in the left-hand lane. Kingsbury also testified that the light turned green, he changed lanes to go around the right side of the stopped car, entered the intersection, and “[a]ll of a sudden there was a collision.” Kingsbury testified that he had activated the siren. Officer Nelson did not testify at trial, but portions of his deposition were read to the jury. Nelson testified that the squad car’s emergency lights and siren were activated when the officers proceeded through the intersection. Nelson stated that he observed the traffic light change from red to green when the squad car was about a block to one-and-one-half blocks from the intersection.
The driver and passenger of the vehicle that was stopped at the light on Washington Avenue testified at trial. The driver testified that he stopped at the light because it had just turned red, he saw emergency lights approach from behind, and he did not hear a siren. The passenger testified that he had his window cracked and first saw the squad car as it passed them, and that “there was definitely no siren there at all.”
The parties do not dispute that the Minneapolis Emergency Communications Center records radio transmissions between officers in squad cars and the dispatch center and that the city’s policy is to reuse or tape over the tapes after 60 days. The tapes only record what is broadcast by radio to and from police officers. Kings-bury agreed that it was “very possible” that Nelson spoke to dispatch again be *860 tween the time of the initial call and the time they reached the intersection where the accident occurred. Kingsbury agreed that if Nelson spoke with dispatch during the period and a tape were made of the conversation, a person might be able to hear the siren if it had been activated. Kingsbury testified that Nelson contacted the dispatcher to report the accident after it occurred.
At the conclusion of trial, the district court instructed the jury that
[t]estimony has been introduced indicating that a police dispatch tape recording existed which may have shown whether a siren was activated and, if so, when it would have been activated. The tape recording was in the possession and control of the City of Minneapolis. The tape recording no longer exists. You are permitted (but are not required) to infer from this fact that the, quote, “siren evidence” is favorable to plaintiff. Weigh this along with all other, quote, “siren testimony” in this case.
The jury returned a verdict for the tow truck operator, finding Kingsbury to be 80% at fault and Wojtowicz to be 20% at fault. The jury specifically found that the siren was not activated. Appellants moved for a new trial, arguing that the district court erroneously instructed the jury that it could take an adverse inference from appellants’ failure to produce a tape that might have corroborated evidence as to the siren. The court denied appellants’ motion for new trial. This appeal follows.
ISSUE
Did the district court abuse its discretion by imposing sanctions for spoliation of evidence?
ANALYSIS
Spoliation is the destruction of evidence.
Federated, Mut. Ins. Co., v. Litchfield Precision Components, Inc.,
First, appellants argue that the district court improperly imposed the sanction of a jury instruction because no evidence shown to exist has been destroyed. But the district court found that credible evidence from the city’s witness established that a recording or recordings were likely to have existed.
See Jorschumb v. Jorschumb,
Second, appellants argue that the district court failed to make a specific finding that the tapes were critical to respondents’ case. But in its order denying appellants’ motion for new trial, the district court stated that “there was testimony * * * that it was likely that an audio recording or recordings were made of events central to the facts of the trial” and that “[t]his testimony demonstrated the relevance of the recording,” whether it supported respondents’ or appellants’ position. Minnesota law requires that officers activate the emergency siren
when responding to an emergency call, upon approaching a red or stop signal or any stop sign shall slow down as necessary for safety, but may proceed cautiously past such red or stop sign or signal after sounding siren and displaying red lights.
Minn.Stat. § 169.03, subd. 2 (2000). As the district court correctly recognized, a “central part” of appellants’ case was the contention that the squad car’s siren was activated during a particular time. Accordingly, the tape was “critical,” and the district court’s finding was not clearly erroneous.
Third, appellants assert that respondents did not suffer prejudice because the city did not obtain an evidentiary advantage over respondents, as it was equally likely that the tape would favor the police officers and not respondents. We disagree. The “workable standard by which to test the impact of the spoliation” is to consider the prejudice to the opposing party.
Patton,
The parties do not dispute that it is unknown what the tapes would reveal; the tapes could favor either party, depending on whether a siren could be heard in the background. But Minnesota “permits an unfavorable inference to be drawn from failure to produce evidence in the possession and under the control of a party to a litigation.”
Federated Mutual Ins.,
Appellants, citing several extra-jurisdictional cases and treatises to support their position, argue that an adverse inference may be taken from the destruction or failure to produce evidence only when the record shows that the evidence was intentionally withheld or destroyed.
See e.g., State by Comm’n. of Transp. v. Council in Div. of Resource Dev.,
The law in Minnesota is that spoliation of evidence need not be intentional to warrant sanctions.
See Patton,
Here, the district court exercised its inherent power to impose the sanction of a jury instruction, concluding that the impact of spoliation was prejudice to the opposing party. The district court found *863 that the city and officers should have known that “litigation or the possibility of litigation was imminent fairly soon after the incident” because the accident involved injuries. Officers Kingsbury and Nelson hired an attorney to pursue their personal injury claims four days after the accident. This was well within the city’s 60-day policy for reusing tapes. The district court denied appellants’ motion for new trial in a ten-page order and memorandum, and, at the hearing on appellants’ motion for new trial, the court discussed at length its intent to deny appellants’ motion and its reasons for doing so. The district court recognized that the record did not reflect any intentional attempt to hide evidence, but the court stated that it “could not ignore, if you will, and I don’t want to make it sound like the Watergate tapes, but could not ignore the missing tape.” The court further gave ample and sound reasons for using its broad authority in determining what, if any, sanction is to be imposed:
I do And, however, that as a matter of policy that the City does have to be held to the same standard as every other litigant that comes in here. And I say that with all due respect realizing some of the burdens that they undertake because of the public nature of their business and the important nature of their business, and especially the importance of the police officers ⅜ * *.
But it is also my opinion that we have to be fair and we have to be held to the same standard. And where you have a car accident such as this with what might have been even more severe injuries * * * [f]rom the fact of an accident alone I think one can anticipate litigation. And at the point where one is anticipating litigation, I think we have to take steps to preserve evidence that’s relevant to the inquiry that may take place, not only of the pictures of the scene and the drawings and the injuries and the medical records and the eyewitness testimony, but also any evidence such as the tape recordings here or any other if you will, any other matters that are helpful to the trier of fact in deciding fault, liability, and/or criminal conduct. * * *
So I think the City should consider changing its policy. And I think that I can understand why they have a policy and the expense to the taxpayers of tape recordings and the difficulty when one combines all the work ⅞ * *, one understands why one might erase at the end of sixty days. I still think we have to be mindful of anticipated litigation in certain areas, and I think steps should be taken to preserve that type of evidence, especially where a squad car might be involved in an accident and we do know that the mere presence of a siren may change the legal status of a party in terms of the immunity available to them.
Not only did the district court express ample reasoning for its decision to exercise its inherent power, but it also chose the least severe of available sanctions. Moreover, we note that because Wojtowicz and two independent witnesses testified that the siren was not activated, any prejudice to appellants as a result of the sanctions, if any, was minimal.
See Kroning v. State Farm Auto. Ins. Co.,
Finally, appellants argue that Patton is limited to spoliation of evidence in product liability cases. But we find no authority limiting Patton to product liability cases. Patton applies to any case where critical evidence has been destroyed. See Patton,
DECISION
The district court did not abuse its discretion by imposing sanctions in the form of a jury instruction permitting an adverse inference against the city for failure to produce the tape recording when the city had exclusive control and possession of the tape, when the tape was critical to the case, and when the destruction prejudiced respondents.
Affirmed.

The Honorable Daniel F. Foley, one of the founding members of this court, who continued to serve by appointment order from the supreme court after his retirement, fully participated in the consideration of this appeal. Due to Judge Foley’s untimely death before the filing of the opinion, Chief Judge Tous-saint has been assigned as a substitute, and now joins the panel in issuing this decision.
