for unlawful arrest and false imprisonment. The statements in the petition are to the effect that at the request and instigation of the defendant the plaintiff was arrested, imprisoned and held in confinement for a period of eighteen hours “without reasonable cause and without right of authority to do so and against the will of this plaintiff.” The answer was a general denial.
*543The evidence on the part of the plaintiff tended to show as follows:
The plaintiff had been the owner of a candy store and was indebted to the defendant in the snm of $1,200, for which defendant held plaintiff’s notes, with certain securities. Plaintiff owed some other debts and the financial conditions not being entirely satisfactory the plaintiff made a bill of sale of the whole establishment to defendant, put the defendant in formal possession and his name on the sign in the place of plaintiff’s. Plaintiff in his testimony claimed that the transaction was only a conditional sale under which the business was to be run in defendant’s name until he could get the money due him and then to be returned to plaintiff, but that it took the form of an absolute sale because defendant’s attorney said it was the only way a valid transaction of that kind could be made. After the execution of this bill of sale and the ostensible transfer of the business, defendant still retained the securities he held for his $1,200 notes. Plaintiff remained (as he claimed, in charge as owner; as defendant claimed, as employee) in the establishment and collected money in the business. On February 6, 1903, a dispute arose between them about an item of $5.30 which plaintiff had collected that.day, and other items amounting to $38 previously collected; plaintiff refused to turn over the money demanded and defendant called in á police officer and told him that plaintiff had committed grand larceny and requested him to arrest the plaintiff which the officer did and further requested the officer to take the plaintiff to the prison and “lock him up” which the officer also did. Defendant went with the officer to the prison and promised the sergeant of police in charge of the station that he would sue out a warrant the next morning. Plaintiff was taken to prison and incarcerated about 5 o ’clock in the afternoon and held until 11 o’clock the next morning; on that morning defendant applied for a warrant, but the *544prosecuting attorney refused it. When plaintiff was brought before the sergeant of police at the Four Courts, he admitted that he had collected the money but claimed that it was his money. When the sergeant was informed that the application for a warrant had been denied he discharged the plaintiff.
The substance of the testimony for the defendant was that the sale was absolute and bona fide, that plaintiff was only an employee and as such had collected the money in dispute and converted it to his own use. That on the morning in question when defendant demanded the money, plaintiff refused; defendant ordered him to leave the store, which he also refused to do; then defendant called in the policeman, told him that the plaintiff was- a trespasser in his store, and had taken $5.30. “I ordered the officer to do his duty; he arrested him, and I accompanied them to the Four Courts. I told the man in charge that he had taken the money, $5.30, and that he refused to return it.” The foregoing is a very brief statement of the facts shown by the evidence in the case, but it is sufficient for an understanding of the law questions involved.
Plaintiff asked three instructions to the following effect:
1. If the defendant caused the plaintiff to be arrested and imprisoned, without process of law, and against plaintiff’s will and so held for a period of eighteen hours, the jury should find for the plaintiff, “and assess his damages in such sum as they believe from the evidence he ought to recover, not exceeding the sum of ten thousand dollars, the amount sued for in the petition.”
2. If the plaintiff was restrained of his liberty at the instance of the defendant without authority or process of law; then in arriving at a verdict the jury should disregard the evidence offered by defendant tending to prove probable cause and want of malice.
3. If the plaintiff “was restrained of his liberty *545at the instance of defendant as charged in the petition,” then it was not necessary for the plaintiff to prove malice or want of probable cause.
Those instructions were refused and exceptions taken.
At the request of defendant the court gave three instructions to the effect as follows:
1. If the jury should find for the plaintiff he could recover only the actual damages he sustained and was not entitled to punitive damages.
2. If the store belonged to defendant, and he ordered the plaintiff to leave it and plaintiff refused and thereupon defendant requested the officer to arrest him and he was so arrested, the plaintiff was not entitled to recover.
3. If defendant was the owner of the store, the plaintiff only an employee, and the plaintiff as employee collected $5 or $30 or any other sum or sums belonging to defendant, refused to pay the same over to defendant but converted the same to his own use, then defendant had a right to order his arrest and the plaintiff cannot recover.
There was a verdict for the defendant and judgment accordingly from which the plaintiff has appealed.
The difference between an unlawful arrest or false imprisonment and a malicious prosecution is this: The wrongdoer in making the unlawful arrest, or causing it to be done, takes the law in his own hands and acts without a warrant from a court or magistrate, while the man who instigates a malicious prosecution puts the machinery of the criminal law into operation, causing a warrant to issue and the arrest under the warrant.
It is the right and privilege of any citizen knowing that one has committed or is in the act of committing a crime to arrest the offender or cause him to be arrested without waiting for a warrant, but in doing so *546the unofficial citizen takes this risk, to-wit, if it should turn out that the man whom he has arrested was not guilty'of the crime, the citizen causing the arrest is liable in a civil action for whatever damages the arrested man sustained in consequence of his- arrest and imprisonment." In such case it is no answer to the plaintiff’s demand for damages for the defendant to say I had reasonable cause to believe the plaintiff was guilty; I acted without malice, I took the advice of counsel learned in the law. The only plea of justification or excuse is that plaintiff was guilty of the crime for which he was arrested. [Ahern v. Collins, 39 Mo. 150; Boeger v. Langenberg, 97 Mo. 390.]
But in an action for malicious prosecution, though it should turn out that the plaintiff was not really guilty of the crime charged, yet if the defendant in putting the machinery of the law into operation acted in good faith, without malice, with reasonable cause to believe the plaintiff guilty and on the advice of counsel to whom all the facts were disclosed, he would not be liable.
The facts of this case illustrate the reason of the law for holding a defendant to a more strict responsibility in the one case than the other. If this defendant had taken the care before causing the arrest and imprisonment of the plaintiff to go to the law officer and lay the facts of the case before him, as he in fact did the next day, there would probably have been no arrest, but he did not take that care; he took the law into his own hands, inflicted the plaintiff with imprisonment first, and sought the advice of the law officer after-wards.
The instructions asked on the part of the plaintiff were in accordance with the law as above expressed and should have been given. The concluding clause of the first instruction relating to the measure of damages is not entirely correct, because the only limitation given is, “such sum as they believe from the evidence he *547ought to recover, not exceeding the sum of ten thousand dollars.” That gives the jury free scope; it should have limited the recovery to a sum which the jury should find from the evidence was necessary and sufficient to compensate the plaintiff for the injury he suffered, there being no claim in the petition for punitive damages. That defect in the instruction is cured by the first instruction given for the defendant, but on a retrial it should be corrected in the instruction itself.
The plaintiff’s third instruction is inaccurate in the use of the words, “as charged in the petition.” The jury knew nothing about the petition and should not be referred to it. Instead of referring the jury to the petition for the character of the arrest, the instruction should have informed the jury on that point. The words, “as charged in the petition,” should be omitted from the plaintiff’s second instruction.
The second and third instructions given at the request of the defendant should have been refused.
The second instruction authorizes the jury to find for the defendant on the theory that the plaintiff was in the defendant’s store and refused to go out of it when lawfully requested, and that the arrest was made for that reason.
In the first place, there was no evidence to support that theory. There was evidence tending to show that it was defendant’s store, that he ordered plaintiff to go out and plaintiff refused, but there was no evidence that for that refusal alone the defendant ordered the arrest. The defendant’s own account of the scene was that when he called the officer in he told him that the plaintiff was a trespasser in his store and that he had stolen the defendant’s money and he wanted him arrested. This was the defendant’s testimony: “I demanded the $5.30; he refused, and I called the officer, told him that the man was a trespasser in my store, took money from me, I want him arrested. I want him put out of the place; he is always troubling, me. *548We came in the store; I again demanded the money from Nick; he said, ‘No, I have got it; I will not give it to you; you can’t bluff me.’ I ordered him out. He said, ‘By — I will not go.’ I ordered the officer to do his duty, he arrested him and I accompanied them to the Four Courts. I told the man in charge that he had taken the money, $5.30; that he refused to return it.” The charge of being a trespasser was coupled with the charge of stealing the money and it was not conceivable that for the mere refusal to leave the store the plaintiff would have been imprisoned.
If it was defendant’s store and plaintiff had no right to be there and refused to go when ordered, defendant had a right to have him ejected, but no right to inflict jail punishment on him.
The third instruction for defendant was to the effect that if the plaintiff as an employee of the defendant collected money of defendant and converted it to his own use, defendant had a right to have him arrested. That is, if the plaintiff was actually guilty of the crime for which the defendant had him arrested the verdict should be for the defendant.
The defendant was not entitled to that instruction, for the reason that it presented an affirmative defense to the action which was not pleaded. The only plea which defendant filed was a general denial. Under that state of the pleadings the plaintiff made out a prima-facie case when he adduced evidence tending to show that the defendant had caused him to be arrested and imprisoned without a warrant. It was not necessary for plaintiff to anticipate an affirmative defense and show that he was not guilty of a crime justifying his arrest. When the arrest and imprisonment without a warrant is proven, the law will presume that it was wrongful until facts are shown to justify it, and those facts must be first pleaded and then proven. It is in this respect like an action for slander. When the defamatory words are proven the defendant will *549be heard either to deny or justify; the one he may do under his plea of general denial, the other he' can do only under a plea of confession and avoidance. [Stark v. Geo. Knapp Pub. Co., 160 Mo. 529.]
In an action for false imprisonment, the defendant under the general denial may introduce evidence which tends to show that he did not cause the arrest, but he cannot prove that he was justified in doing so, unless he has pleaded the facts in justification. [Hoagland v. Amusement Co., 170 Mo. 342; Thompson v. Buchholz, 107 Mo. App. 121; 1 Hilliard on Torts, p. 212, sec. 5; 8 Ency. P. & P., 850.] Whether objections were made to the evidence of defendant tending to show justification on the ground that no such defense was pleaded, does hot appear in the abstract of the record before us, and perhaps if there was no other error in the record it would be proper to say that since the plaintiff made no such objection but allowed the evidence to go in, the giving of the instruction submitting an issue to the jury which though not raised by the pleadings yet was based on that evidence, was not reversible error, but since for the other errors above mentioned the judgment will be reversed, we have considered it proper to bring this point to the attention of the trial court for its guidance in the new trial.
For the errors in refusing the plaintiff’s instructions and the giving of defendant’s second instruction, the judgment is reversed and the cause remanded to the circuit court to be retried according to the law as herein expressed.
All concur, except Graves, J., not sitting.
