Larry Crandall Roberts appeals his judgments and sentences for two counts of aggravated assault with a firearm following a nonjury trial. Roberts's sole argument on appeal is that the trial court erred in rejecting both his statutory1 and common law affirmative defenses2 of citizen's arrest regarding his use of a shotgun while attempting to detain two unarmed individuals,3 whom he believed had committed a felony.
A detailed recitation of the facts is unnecessary to our resolution. While we agree with Roberts that he initially had probable cause to effect a citizen's arrest, the State presented evidence at trial contradicting *876Roberts's affirmative defense by showing that he did not act in a reasonable manner when he attempted to detain the two individuals. This factual dispute regarding the affirmative defense was resolved by the trier of fact adversely to Roberts, and the record contains competent substantial evidence supporting his convictions.
AFFIRMED .
Evander, Lambert, and Eisnaugle, Associate Judges,4 concur.
