Before: DOCTOROFF, P.J., and SAWYER and FITZGERALD, JJ.
PER CURIAM.
In this negligence action, plaintiff appeals as of right from the trial court's order granting *178 summary disposition in favor of defendant[1] pursuant to MCR 2.116(C)(8) and (10) and denying plaintiff the opportunity to amend her complaint. We reverse.
Plaintiff attended the PlanetFest concert, at which several bands were scheduled to appear, at the Pine Knob Music Theater. The Pine Knob Music Theater is an outdoor amphitheater, offering reserved seating in a pavilion and open seating on a grass-covered hill. Plaintiff received tickets to the concert as part of a promotional giveaway by a local radio station sponsoring the concert. Plaintiff arrived at the Pine Knob Music Theater with a friend and found a spot to sit on the hill. Sometime later, while one of the bands was performing, a few individuals on the hill began to pull up sod and throw the sod at others. In previous years, there had been two sod-throwing incidents at the theater. Before the show, the event coordinator had asked that the bands stop performing and announce that the sod throwing must stop if audience members began throwing sod. Pursuant to the event coordinator's request, the band stopped performing, made the announcement, and refused to continue its performance until the sod throwing stopped. The crowd complied and several individuals involved in the incident were ejected from the theater. Approximately forty-five minutes later, while a different band was performing, the sod throwing began again. When the band refused to make an announcement or to stop performing until the sod throwing stopped, the event coordinator made an announcement demanding that the sod throwing stop. When the sod throwing continued, the band made an additional announcement. Numerous individuals involved in the incident were ejected from the theater. However, plaintiff fractured her ankle when she fell in an attempt to avoid a large piece of sod thrown in her direction.
Plaintiff filed a complaint alleging that defendant was negligent in failing to provide proper security, failing to stop the performance when it should have known that continuing the performance would incite the crowd, failing to screen the crowd to eliminate intoxicated individuals, and by selling alcoholic beverages. Defendant filed a motion for summary disposition pursuant to MCR 2.116(C)(8) and (10), arguing that it did not have a duty to protect plaintiff from the criminal acts of third parties. The trial court granted defendant's motion on that basis.
Plaintiff first argues that the trial court erred in granting summary disposition in favor of defendant pursuant to MCR 2.116(C)(8) and (10). We agree. We review de novo the grant or denial of a motion for summary disposition. Int'l Brotherhood of Electrical Workers, Local Union No. 58 v. McNulty, 214 Mich.App. 437, 442, 543 N.W.2d 25 (1995). A motion for summary disposition pursuant to MCR 2.116(C)(8) tests the legal sufficiency of a claim by the pleadings alone. Simko v. Blake, 448 Mich. 648, 654, 532 N.W.2d 842 (1995). All factual allegations supporting the claim are accepted as true, as well as any reasonable inferences or conclusions that can be drawn from the facts. Marcelletti v. Bathani, 198 Mich.App. 655, 658, 500 N.W.2d 124 (1993). The motion should be granted only when the claim is so clearly unenforceable as a matter of law that no factual development could possibly justify a right of recovery. Wade v. Dep't of Corrections, 439 Mich. 158, 163, 483 N.W.2d 26 (1992).
A motion for summary disposition pursuant to MCR 2.116(C)(10) tests the factual support for a claim. Amorello v. Monsanto Corp., 186 Mich.App. 324, 329, 463 N.W.2d 487 (1990). Such a motion may be granted when there is no genuine issue of material fact and the moving party is entitled to judgment as a matter of law. Id. Giving the benefit of doubt to the nonmovant, this Court must determine whether a record might be developed that will leave open an issue upon which reasonable minds could differ. Bertrand v. Alan Ford, Inc., 449 Mich. 606, 618, 537 N.W.2d 185 (1995).
To establish a prima facie case of negligence, a plaintiff must demonstrate that *179 (1) the defendant owed a duty to the plaintiff,(2) the defendant breached that duty, (3) the defendant's breach of its duty was the proximate cause of the plaintiff's injury, and (4) the plaintiff suffered damages. Richardson v. Michigan Humane Society, 221 Mich.App. 526, 528, 561 N.W.2d 873 (1997). Plaintiff argues that the trial court erred in finding that the sod-throwing incident was not foreseeable and, therefore, defendant did not have a duty to protect plaintiff. Plaintiff further argues that the trial court erred in concluding as a matter of law that defendant used reasonable care to protect its invitees from such activities.
Generally, there is no duty to protect against the acts of a third person. Marcelletti, supra at 664, 500 N.W.2d 124. However, an exception to this general rule exists where there is a special relationship between the defendant and the plaintiff, or between the defendant and the third person. Id. One of the special relationships that will impose a duty to protect against the acts of third parties is the relationship between an occupier of land and its invitees. Williams v. Cunningham Drug Stores, Inc., 429 Mich. 495, 499, 418 N.W.2d 381 (1988). Ordinarily, merchants do not have a duty to provide security guards to protect customers from the criminal acts of third parties. Id. at 504, 418 N.W.2d 381. However, invitors have a duty to use reasonable care to protect their identifiable invitees from the foreseeable criminal acts of third parties. Mason v. Royal Dequindre, Inc., 455 Mich. 391, 405, 566 N.W.2d 199 (1997).
Ordinarily, whether a duty exists is a question of law for the court to decide. Id. at 397, 566 N.W.2d 199. However, where the determination of duty depends on factual findings, those findings must be made by the jury. Holland v. Liedel, 197 Mich.App. 60, 65, 494 N.W.2d 772 (1992). Whether the risk of harm from third-party criminal activity is foreseeable in a particular case is generally a question of fact for the jury. Id. at 63, 494 N.W.2d 772. Here, in response to defendant's motion for summary disposition, plaintiff submitted evidence that there had been incidents of sod throwing at previous concerts and that defendant was aware of those incidents. Plaintiff also presented evidence that defendant had formulated policies to deal with sod-throwing incidents before the PlanetFest concert. Accordingly, at the very least, a genuine issue of material fact existed with respect to whether the sod-throwing incident was foreseeable. Therefore, the trial court erred in granting summary disposition in favor of defendant pursuant to MCR 2.116(C)(10) after finding that the risk of harm from the sod-throwing incident was not foreseeable.
Plaintiff next argues that the trial court erred in determining as a matter of law that defendant used reasonable care to protect her from injury. The reasonableness of a defendant's conduct is generally a question for the jury. Riddle v. McLouth Steel Products Corp., 440 Mich. 85, 96, 485 N.W.2d 676 (1992). However, questions concerning reasonable care may be determined by the court as a matter of law if there are overriding concerns of public policy. Scott v. Harper Recreation, Inc., 444 Mich. 441, 448, 506 N.W.2d 857 (1993). Here, in support of its motion for summary disposition, defendant submitted evidence that it provided approximately forty security officers during the concert, and that approximately eleven officers from the Oakland County Sheriff's Department were working at the concert. Defendant also submitted evidence that it stopped the show on three separate occasions in an effort to stop the sod throwing. In response, plaintiff submitted the affidavit of its expert witness, stating that defendant was negligent in failing to have adequately trained security personnel properly positioned at the concert, failing to summon police to eject or arrest those throwing sod, failing to have a clear, written policy regarding sod throwing, allowing the concert to continue after the first sod-throwing incident, and serving alcohol. Accordingly, a genuine issue of material fact existed with respect to whether the security measures taken by defendant were reasonable, and the trial court erred in granting defendant's motion for summary disposition pursuant to MCR 2.116(C)(10).
Furthermore, taking as true the allegations in plaintiff's complaint, we cannot *180 conclude that plaintiff's negligence claim is so clearly unenforceable as a matter of law that no factual development could possibly justify a right to recovery. Wade, supra at 163, 483 N.W.2d 26. Plaintiff's complaint sufficiently alleged the elements of a negligence claim. See Jackson v. White Castle System, Inc., 205 Mich.App. 137, 517 N.W.2d 286 (1994) (holding that the plaintiff stated a claim upon which relief could be granted in alleging that the defendant property owner failed to control or eject unruly patrons and failed to notify police when it knew or should have known that patrons were in danger). Therefore, defendant was not entitled to summary disposition of plaintiff's negligence claim pursuant to MCR 2.116(C)(8).
Next, plaintiff asserts that the trial court erred in denying her motion to amend her complaint. We agree. A trial court's decision regarding a motion to amend a pleading is reviewed on appeal for an abuse of discretion. Weymers v. Khera, 454 Mich. 639, 654, 563 N.W.2d 647 (1997).
Plaintiff sought to amend her complaint pursuant to MCR 2.116(I)(5). If a court grants summary disposition pursuant to MCR 2.116(C)(8), (9), or (10), the court must give the parties an opportunity to amend their pleadings pursuant to MCR 2.118, "unless the evidence then before the court shows that amendment would not be justified" or would be futile. MCR 2.116(I)(5); Weymers, supra at 658, 563 N.W.2d 647. Ignoring the substantive merits of a claim, an amendment is futile if it is legally insufficient on its face. McNees v. Cedar Springs Stamping Co., 184 Mich.App. 101, 103, 457 N.W.2d 68 (1990). Here, plaintiff sought to add nuisance, negligent design, and third-party beneficiary claims, and to more specifically set forth her negligence claim. Plaintiff's proposed claims were not legally insufficient and were justified by the evidence before the court. Accordingly, we conclude that the trial court abused its discretion in denying plaintiff's motion to amend her complaint.
Reversed.
NOTES
[1]  Because defendant Capital Cities/ABC, Inc., was dismissed with prejudice before the trial court's order granting summary disposition, we will refer to defendant PKT, Inc., also known as Pine Knob Music Theater and Arena Associates, as "defendant" throughout this opinion.
