*255OPINION
By the Court, Rose, J.:A jury found appellants William L. Yada and the Las Vegas Metropolitan Police Department (LVMPD) liable to respondent Fred Joseph Simpson for false imprisoninent and battery. We reverse the judgment with respect to the claim of false imprisonment and the award of attorney’s fees to Simpson. We affirm the judgment with respect to the claim of battery.
FACTS
Early in the morning on August 6, 1986, Simpson and some friends were in a jacuzzi at the apartment complex where Simpson lived. Officer Yada responded to a call from a security officer at the complex, who complained that the group in the jacuzzi was too loud. Yada ordered Simpson and the others from the jacuzzi. When Simpson stated that he had a right to remain, Yada declared that he was under arrest. At trial, the parties offered conflicting evidence as to how Yada and Simpson each acted. Simpson presented evidence that Yada, another police officer, and two security officers used excessive force in arresting him. Yada presented evidence that Simpson had aggressively resisted the arrest and that only moderate force was used against him.
Yada arrested Simpson and charged him with battery on an officer, resisting arrest, assault, disorderly conduct, and disturbing the peace. In his declaration of arrest, Yada indicated that the battery on an officer was a misdemeanor charge. However, the jail booked Simpson for felony battery on an officer and set bail for that charge at $5,000. The bail for all five charges totaled $8,750. Simpson stayed in jail for nearly a week. He was ultimately charged by criminal complaint with battery, resisting arrest, and disturbing the peace. The justice of the peace later found him guilty of resisting arrest and not guilty of battery and disturbing the peace.
On August 7, 1988, Simpson sued Yada, the LVMPD, and some other defendants, alleging false arrest, false imprisonment, malicious prosecution, assault, and battery. The jury found Yada and the LVMPD liable for battery and false imprisonment and awarded $12,500 for the false imprisonment and $50,000 for the battery, for a total judgment of $62,500. The district court *256directed Yada and the LVMPD to pay Simpson’s attorney’s fees of $10,000.
DISCUSSION
False Imprisonment
It is established that Simpson’s arrest was valid: the justice of the peace found that Simpson had committed the offense of resisting arrest, and the civil jury rejected his claim of false arrest. “The plaintiff in a false imprisonment action bears the burden of proving that the delay following his valid arrest was unlawful. A few hours may constitute an unnecessary delay; whether the defendant proceeded with due diligence depends on the circumstances of the particular case.” Nelson v. City of Las Vegas, 99 Nev. 548, 554, 665 P.2d 1141, 1145 (1983) (citations omitted). In Nelson, the arresting officer’s “potential liability for delay ceased when he promptly turned [the plaintiff] over to the officers who were responsible for taking [the plaintiff] to jail.” Id. at 555, 665 P.2d at 1145.
No evidence shows that Yada acted without due diligence in turning Simpson over to officers who placed Simpson in jail. Simpson’s theory of false imprisonment appears to have been that Yada intentionally charged him with four “false charges,” causing his bail to be excessive and preventing him from posting bail. However, we conclude that Yada’s confrontation with Simpson provided him with probable cause to arrest Simpson for disturbing the peace, disorderly conduct, assault, and battery on an officer, even though these charges were either never prosecuted or never proven beyond a reasonable doubt. Further, assuming that setting an excessive amount of bail can constitute false imprisonment, Simpson never showed that Yada or the LVMPD were responsible for setting the amount of bail. The record shows that the admitting officers at the jail set the bail amounts and charged Simpson with felony battery on an officer even though Yada intended the charge to be a misdemeanor. Nor did Simpson show that he attempted to post bail but was unable to because of the bail amount. We therefore conclude as a matter of law that false imprisonment was not established in this case.
Battery
The jury found that Yada had committed a battery in arresting Simpson. The jury was instructed that “a police officer who uses more force than is reasonably necessary to effect a lawful arrest commits a battery upon the person arrested.” The evidence on *257this issue was conflicting, but Simpson offered the testimony of other eyewitnesses, in addition to his own, indicating that Yada used unnecessary force in arresting him. This court will not overturn a jury verdict if it is supported by substantial evidence, unless the verdict is clearly erroneous in light of all the evidence presented. Frances v. Plaza Pacific Equities, 109 Nev. 91, 94, 847 P.2d 722, 724 (1993). We conclude that there was adequate evidence for a reasonable jury to find that a battery occurred.
Attorney’s Fees
Simpson made a joint offer of judgment of $50,000 to Yada, LVMPD, and another defendant. The defendants rejected it. The offer did not state to what extent each defendant was liable. The district court awarded Simpson attorney’s fees because after trial Simpson obtained an award greater than the one he had offered the defendants.
NRCP 68 provides that an offeree who obtains a judgment no more favorable than a rejected offer of judgment must pay attorney’s fees and costs of the other party, if any are allowed. NRS 17.115(4) has substantially the same provision. Since we have rejected the false imprisonment claim and damages, the judgment obtained by Simpson was not more favorable than his offer of judgment. But further, in prior cases, this court has consistently concluded that unapportioned offers of judgment are an invalid basis for the award of attorney’s fees.
An offer of judgment made to multiple plaintiffs but unappor-tioned between them was invalid as a basis for the award of attorney’s fees in Ramadanis v. Stupak, 104 Nev. 57, 59, 752 P.2d 767, 768 (1988). Similarly, an offer of judgment made by multiple plaintiffs but not apportioned between them was invalid in Morgan v. Demille, 106 Nev. 671, 674-75, 799 P.2d 561, 562-63 (1990). In Bergmann v. Boyce, 109 Nev. 670, 856 P.2d 560 (1993), a defendant failed to apportion his offer of judgment between three plaintiffs, the plaintiffs rejected it, and the defendant prevailed at trial. This court refused to recognize an exception to the rule invalidating unapportioned offers even where the defendant was found to have no liability and thus clearly received a more favorable result than the offer he made. We reasoned that NRCP 68 is intended to encourage settlements but that unappor-tioned joint offers do not serve that end: “Individual offerees, unable to determine their share of a joint offer, cannot make a meaningful choice between accepting the offer or continuing the litigation to judgment.” Id. at 678, 856 P.2d at 565. We therefore concluded that “the better rule is to hold all unapportioned joint *258offers of judgment invalid regardless of the outcome of the trial on the merits.” Id.
The rule and its rationale apply also to the instant case, where a single plaintiff’s offer of judgment was not apportioned among multiple defendants. Such an offer of judgment does not serve to encourage settlement since the individual defendants are unable to determine their share of a joint offer and make a meaningful choice between accepting the offer or continuing to litigate. Therefore, Simpson’s offer of judgment was an invalid basis for the award of attorney’s fees, and the district court erred in ordering the payment of fees.
CONCLUSION
The verdict of $12,500 for false imprisonment was clearly erroneous, and we therefore reverse the district court’s judgment in this regard. We also reverse the award of attorney’s fees. We affirm the judgment of $50,000 for battery since there was substantial evidence to support it,
