OPINION
Robert Burge (defendant) petitioned for review of the court of appeals’ decision *26 affirming his conviction on two counts of aggravated assault and his sentence on count II. 1 He challenged the court’s holding that a separate allegation of dangerousness, while preferred, is not required. We granted review to resolve inconsistencies in this court’s prior opinions on how one must allege dangerousness for the purposes of sentence enhancement under A.R.S. § 13-604. We have jurisdiction pursuant to Ariz. Const, art. 6, § 5(3), and A.R.S. § 12-120.24.
FACTUAL AND PROCEDURAL BACKGROUND
The Cochise County Grand Jury indicted defendant on two counts of aggravated assault for stabbing a person using a knife with a five- to six-inch blade. The victim received an eighteen- to twenty-inch wound in his stomach and a gaping hole in his back. Count I charged defendant with aggravated assault causing serious physical injury in violation of A.R.S. § 13-1204(A)(1), and count II charged him with aggravated assault using a deadly weapon or dangerous instrument in violation of § 13-1204(A)(2). Both counts mirrored § 13-1204’s language and included a citation to § 13-604. 2 Neither count, however, alleged the specific physical injury, deadly weapon, or dangerous instrument involved, and the prosecution made no separate allegation of dangerousness.
The trial jury returned guilty verdicts against defendant on both counts. Prior to the trial court’s entry of judgment and sentence, defendant filed a sentencing memorandum challenging the court’s authority to sentence him as a dangerous offender. The court, however, found both offenses dangerous pursuant to § 13-604, and sentenced defendant to a mitigated five-year term on each count, both terms to run concurrently.
Defendant then filed a motion to reconsider the sentence, again challenging the court’s authority to sentence him as a dangerous offender. The trial court denied the motion and defendant appealed. The court of appeals held that a separate allegation of dangerousness, although preferred, is not required.
State v. Burge,
No. 2 CA-CR 89-0479, slip op. at 3 (Ariz.Ct.App. Apr. 10, 1990) (mem.) (per curiam) (citing
State v. Tresize,
DISCUSSION
A.R.S. § 13-604(K) provides that penalties shall be enhanced if, inter alia,
the dangerous nature of the felony ... is charged in the indictment or information and admitted or found by the trier of fact. The court shall allow the allegation of ... the dangerous nature of the felony ... at any time prior to the date the case is actually tried unless the allegation is filed fewer than twenty days before the case is actually tried and the court finds on the record that the defendant was in fact prejudiced by the untimely filing and states the reasons for these findings____ For the purposes of this subsection, “dangerous nature of the felony” means a felony involving the use or exhibition of a deadly weapon or dangerous instrument or the intentional or knowing infliction of serious physical injury upon another. (Emphasis added.)
*27
Under this statute, before a defendant may be sentenced under the enhanced punishment provisions, dangerousness must be charged in the information or indictment.

State v. Whitney,
In this case, the grand jury indictment clearly charged dangerousness by including a citation to § 13-604 in each count. Defendant, however, argues that the rule is well established that the state, not the grand jury, must allege dangerousness to invoke § 13-604’s sentence enhancement provisions.

For this proposition, defendant cites
Barrett
and
State v. Birdsall,
We first considered this issue in
Bird-sall.
In
Birdsall,
a grand jury indicted the defendant for first degree burglary.
On review, this court held that the trial court abused its discretion in dismissing the allegation of prior conviction.
Id.
at 114,
We addressed a similar issue only three years later in
Tresize.
The indictment there charged the defendant with “taking or retaining the property while an accomplice was armed with a deadly weapon or used or threatened to use a deadly weapon or dangerous instrument, a pistol____”
Tresize,
Two years later in Barrett, we grappled with the issue yet again. The information there charged the defendant with causing the victim’s death with premeditation, and included a citation to § 13-604. In what the State here argues is dictum because Barrett involved a defendant charged by information rather than by indictment, we stated:
“[Tjhey [the grand jurors] have no authority to add allegations to the indictment which are concerned with punishment. * * * ” Birdsall,116 Ariz. at 113-14 ,568 P.2d at 420-21 . If charges are brought by indictment, therefore, it becomes necessary for the state to file an allegation of dangerous nature prior to trial.
Barrett,
Birdsall
and
Barrett
are inconsistent with
Tresize.
We now believe that
Birdsall
and
Barrett
were incorrectly decided.
Birdsall
acknowledged that the predecessor to § 13-604
“implies
that the grand jury may have the power to allege a prior conviction in the indictment,” but stated that this implied power is inconsistent with the grand jury’s specified duties.
DISPOSITION
We affirm defendant’s convictions on counts I and II, and his sentence on count II. We vacate the sentence on count I and remand this case to the trial court to resen-tence defendant as a nondangerous offender on that count. We vacate those portions of the court of appeals’ memorandum decision that are inconsistent with this opinion.
Notes
. The court of appeals vacated the sentence on count I and remanded it to the trial court for resentencing because the jury did not specifically find dangerousness. The court affirmed the sentence on count II, despite the lack of a specific jury finding of dangerousness, reasoning that aggravated assault using a deadly weapon or dangerous instrument is necessarily dangerous and an enhanced sentence was therefore proper.
. The indictment reads:
COUNT I
On or about the 3rd day of March, 1989, BOBBY BURGE, committed an aggravated assault upon [the victim], causing serious physical injury, in violation of A.R.S. §§ 13-1203, 13-1204(A)(1), 13-604, 13-701 and 13-801, [ (]a class 3 felony).
COUNT II
On or about the 3rd day of March, 1989, BOBBY BURGE, committed an aggravated assault upon [the victim], using a deadly weapon or dangerous instrument, in violation of A.R.S. §§ 13-1203, 13-1204(A)(2), 13-604, 13-701 and 13-801, (a class 3 felony).
. The trial court, however, may allow the allegation of dangerousness after the information or indictment at any time prior to trial in cases in which there is no prejudice to the defendant.
State v. Whitney,
. Defendant does not claim that he had no notice that the State was seeking an enhanced sentence. Nor could he make this claim. The recital of § 13-604 in the indictment gives sufficient notice that the State will seek an enhanced sentence.
State v. Littles,
. In reaching this conclusion, we relied on Arizona statutes defining the role of county grand juries. These statutes indicate that the grand jury’s role is to inquire into and charge “public offenses." See A.R.S. §§ 21^101(1) & (2), 21-407(A) & (B); see also Ariz.R.Crim.P. 13.1(a), 17 A.R.S. (defining “indictment”).
. Section 13-1649 was a predecessor to § 13-604. In language substantially similar to the relevant language of § 13-604, former § 13-1649(B) provided: "The punishments prescribed by this section shall be substituted for those prescribed for a first offense if the previous conviction is charged in the indictment or information____” (Emphasis added).
. We are aware of two other cases that have cited
Birdsall
and/or
Barrett
with approval. To the extent they state that a grand jury allegation of dangerousness in an indictment is invalid to invoke § 13-604’s sentence enhancement provisions,
State v. Littles,
