On 12 February 1995, defendant was driving his truck when he noticed a signal on his CB radio. He identified the signal as one coming from a person attempting to block the signal of others. Defendant tracked the signal to a location at Smalls Chapel Church. He then tried to block the signal he had been tracking. After approximately five minutes, he was approached by Randy Moye (Moye), along with his son, Joey Moye, and his neighbor, James Lassiter (Lassiter). Defendant testified that he and Moye exchanged words, and that Moye cursed and threatened him. Defendant further testified that after this exchange, Moye reached under his coat and pulled out a gun, but the gun caught on his coat and fell to the ground. Upon seeing Moye reach for the gun on the ground, defendant pulled out his own gun and fired three shots in Moye’s direction. Defendant testified that he shot Moye in self-defense because he feared for his life. Moye testified that he and defendant did not know each other before the day of the incident, that he did not threaten defendant, and that he attempted to pull his gun out only after seeing defendant had a gun.
*724Defendant was charged with assault with a deadly weapon with intent to kill inflicting serious injury. The trial court instructed the jury on self-defense; however, defendant was convicted of assault with a deadly weapon inflicting serious injury. The trial court sentenced defendant to a minimum 17 months and a maximum 30 months in the custody of the Department of Corrections and recommended that defendant pay restitution in the amount of $82,000.00.
[1] In his first assignment of error, defendant contends that the trial court erred by locking the courtroom doors during his trial, thereby denying his right to a public trial as guaranteed by N.C. Const, art. I, § 18 and U.S. Const, amends. VI and XIV, § 1. To prove the doors were locked, defendant argues that a witness that was to testify on his behalf was not present in the courtroom upon being called to the stand. When the witness did not appear, defense counsel stated, “I don’t know if maybe she’s out there and they won’t let her come in.” (T. at 127).
We first note that defendant did not object to the doors being locked, if in fact they were locked. According to N.C.R. App. P. 10(b), “[i]n order to preserve a question for appellate review, a party must have presented to the trial court a timely request, objection or motion, stating the specific grounds for the ruling the party desired the court to make ....” Because defendant did not object to the doors being locked, he has failed to preserve the question for appellate review. However, even if this assignment of error was properly before us, we would find that defendant was not denied his constitutional right to a public trial. It is unclear from the record whether the doors were in fact locked, or whether anyone was prevented from entering or exiting the courtroom. In addition, there is no indication in the record as to why the witness was not present, what she would have testified to, or whether defendant was prejudiced because she did not testify. We therefore find defendant’s first assignment of error to be without merit.
[2] In his second assignment of error, defendant contends that the trial court erred by limiting defense counsel’s cross-examination of Moye regarding evidence of a prior assault charge against him for which he was acquitted. Defendant argues that such evidence is admissible pursuant to N.C.R. Evid. 404(b) to establish Moye’s motive, opportunity, common plan, and absence of mistake on the day of the encounter, and to support his claim that he shot Moye in self-defense.
*725As the State correctly points out, this assignment of error refers to pages of the transcript that contain the cross-examination of Lassiter rather than Moye. However, we elect to address this assignment of error as it was otherwise properly brought forward by defendant.
According to N.C.R. Evid. 404(b), evidence of prior bad acts is inadmissible to prove action in conformity with character. It is, however, admissible for other purposes, such as to show motive, opportunity, common plan, and absence of mistake. After Moye testified that he had been acquitted of the assault charge, the trial court sustained the State’s objection. Defendant, however, failed to establish that this evidence would show motive, etc. on the part of Moye. In any event, defendant was permitted to cross-examine Moye about his history of prior bad acts, including convictions for assault and communicating threats, incidents of Moye impersonating a police officer and frequently blocking CB signals. Therefore, since defendant was permitted to elicit testimony from Moye regarding other prior bad acts, we fail to see how defendant was prejudiced by the trial court’s limitation of defendant’s cross-examination of Moye as to this one incident.
[3] In his third assignment of error, defendant contends that the trial court erred in refusing to allow evidence of Moye’s character under N.C.R. Evid. 404(a)(2) in order to show that he was the aggressor in this altercation.
While evidence of character is generally inadmissible, N.C.R. Evid. 404(a)(2) provides that evidence of pertinent character traits of a victim offered by an accused is admissible. N.C.R. Evid. 405(b) allows for proof of character by evidence of specific instances of conduct in cases where character is an essential element of a charge, claim or defense. Where defendant argues he acted in self-defense, evidence of the victim’s character may be admissible for two reasons: “to show defendant’s fear or apprehension was reasonable or to show the victim was the aggressor.” State v. Watson, 338 N.C. 168, 187, 449 S.E.2d 694, 706 (1994), cert. denied, - U.S. -, 131 L. Ed. 2d 569, rev’d on other grounds, State v. Richardson, 341 N.C. 585, 461 S.E.2d 724 (1995).
Evidence of a victim’s violent character is relevant to prove that defendant’s apprehension and need to use force were reasonable if defendant had knowledge of the victim’s character at the time of the encounter. State v. Shoemaker, 80 N.C. App. 95, 101, 341 S.E.2d 603, *726607, cert. denied, 317 N.C. 340, 346 S.E.2d 145 (1986). In the present case, defendant did not know Moye nor did he know anything about his reputation prior to the altercation. Thus, evidence of specific instances of Moye’s violent character was irrelevant in regards to the reasonableness of defendant’s apprehension and need to use force, and the trial court properly denied its admission on this basis.
However, evidence of specific instances of a victim’s character, “known or unknown to the defendant at the time of the crime,” may be relevant in establishing that the victim was the aggressor when defendant claims self-defense. Watson, 338 N.C. at 188, 449 S.E.2d at 706 (citations omitted). Defendant attempted to elicit such evidence by asking Lassiter “[h]ave you ever known Mr. Moye to ever pull a pistol on anyone else out there where you live?” (T. at 75).
In Watson, our Supreme Court stated that while evidence was excluded regarding the victim’s violent character, the trial court allowed other evidence concerning his character. Id. Also, the Court noted that defendant failed to make an offer of proof so as to place the witness’ response to the question in the record. Id. The Court further held: “[I]n order for a party to preserve for appellate review the exclusion of evidence, the significance of the excluded evidence must be made to appear in the record and a specific offer of proof is required unless the significance of the evidence is obvious from the record.” Id. (citations omitted). Likewise, here the trial court permitted other evidence which reflected on Moye’s character and defendant did not assert or make an offer of proof showing what Lassiter’s response would have been. Therefore, we cannot assess the significance of the evidence sought to be elicited and this assignment of error is overruled.
In his fourth assignment of error, defendant contends that the trial court abused its discretion by failing to find extraordinary mitigating factors and impose an intermediate punishment. The trial court did not find any aggravating factors but found the following four mitigating factors: (1) that defendant committed the offense under threat which was insufficient to constitute a defense but significantly reduced his culpability; (2) that defendant has been a person of good character or has had a good reputation in the community; (3) that defendant supports his family; and (4) that defendant has a positive employment history or is gainfully employed.
[4] Defendant contends that the trial court could also have found as extraordinary mitigating factors that he has a support system in the *727community, that he acted under strong provocation, and that he had a medical condition that reduced his culpability. Further, the trial court could have imposed an intermediate punishment under N.C. Gen. Stat. § 15A-1340.13(g) (Cum. Supp. 1996). However, the decision to impose an intermediate punishment pursuant to this statute is within the discretion of the trial court. Id. In light of the evidence in this case, the trial court did not abuse its discretion by failing to impose an intermediate punishment.
[5] In his final assignment of error, defendant contends that the trial court erred in recommending that he pay restitution to Medicaid in the amount of $82,000.00 as a condition of post release supervision. He argues that the recommendation is not supported by the evidence and is beyond his ability to pay.
At defendant’s sentencing hearing, Moye stated, upon inquiry by the trial court, that Medicaid paid his medical bills totalling $82,000.00. Defendant did not object or challenge the amount or existence of the payments by Medicaid. N.C. Gen. Stat. §§ 148-33.2(c), -57.1(c) (1994) provides that the trial court’s order of restitution as a condition of work release or parole is a recommendation to the Secretary of the Department of Correction and the Parole Commission, and not an order binding defendant to pay restitution in the amount stated in the judgment. State v. Wilson, 340 N.C. 720, 725-26, 459 S.E.2d 192, 195 (1995). If the Department of Correction or the Parole Commission decides that defendant should pay restitution as a condition of work release or parole, a determination of his ability to pay will be made at that time. See id. Thus, the trial court did not err by recommending that defendant make restitution to Medicaid in the amount of $82,000.00.
For the above reasons, we conclude that defendant received a fair trial free from prejudicial error.
No error.
