Johnny Wayne Petty appeals his conviction for aggravated assault and the sentence imposed after the trial court revoked his probation in an earlier robbery case. Appellant contends that his aggravated assault conviction must be reversed because the State failed to prove an element of the offense. Concerning the sentence in the robbery case, he complains that the trial court considered matters unsupported by any evidence when it assessed his punishment. We affirm the trial court’s judgments in both cases.
Aggravated Assault
On September 13,1984, two Dallas police officers responded to a disturbance complaint. When they arrived at the scene, three agitated witnesses reported that a man had been yelling at them. The officers testified that the witnesses told them that he had called them prostitutes and had asked one of them to “work for him” as “his girlfriend.” The witnesses told the officers that they had refused his solicitations and that appellant had refused their repeated requests to leave them alone. During this conversation, one of the witnesses saw appellant walking on the other side of the street. All three witnesses identified him as the man who harassed them; therefore, the officers decided to question appellant and to instruct him not to bother the three women again. However, appellant ignored the officers’ requests to stop and rapidly walked between two buildings. The officers followed, eventually detained him, and conducted a pat-down search for weapons. According to the officers, appellant reluctantly surrendered his identification. While one officer questioned appellant about the disturbance, the other requested by radio a check for outstanding arrest warrants. The officers testified that the warrant check was a part of their routine procedure during an investigatory stop. One of the officers stated at trial that they did not intend to arrest appellant for the disturbance when they requested his identification. Three to five minutes after the officers requested the check, however, they learned of a warrant for appellant’s arrest for violating the conditions of his probation in the robbery case. The officers told appellant that he was under arrest, handcuffed him, and attempted to place him in the back seat of their patrol car. Appellant struggled and kicked one of the officers in the groin. Consequently, appellant was convicted by the court of aggravated assault.
Under sections 22.01 and 22.02 of the Penal Code, a person is guilty of aggravated assault if he intentionally, knowingly or recklessly causes bodily injury to a peace officer “when the person knows or has been informed the person assaulted is a peace officer ... [who] is lawfully discharging an official duty.” Tex. Penal Code Ann. §§ 22.01(a)(1), 22.02(a)(2) (Vernon Supp.1985). Appellant claims that the officer assaulted was not lawfully discharging an official duty when the assault occurred because the arrest resulted from an unconstitutional detention. He concludes, therefore, that his arrest was illegal because it resulted from an unreasonable seizure in violation of the fourth amend *637 ment. 1 U.S. Const, amend. IV. We hold the detention did not violate the fourth amendment and that the officer was acting lawfully when he arrested appellant.
When the officers restricted appellant’s freedom of movement and requested his identification, they seized appellant for purposes of fourth amendment analysis.
Terry v. Ohio,
Even though the investigatory stop was “justified at its inception,” appellant argues that it became unreasonable because the officers held him solely to check for arrest warrants, a purpose which he claims is not “reasonably related in scope to the circumstances ... justifying] the interference.” Appellant reasons that, since the officers had already decided not to arrest him for the disturbance, they could not legally detain him pending the completion of the check unless they had probable cause to believe that there was a warrant for his arrest. Appellant, further reasons that, since his continued detention was illegal, the resulting arrest was illegal; therefore, he concludes that the officer was not lawfully discharging his duty when he was assaulted.
We recognize that an investigative stop can last no longer than necessary to effect the purpose of the stop absent probable cause to arrest the person or the person’s consent.

See Florida v. Royer,
*638
Nevertheless, we must still decide whether checking for outstanding arrest warrants during an otherwise valid investigatory stop is so unrelated in scope to the purpose of the detention that it renders the stop unconstitutional. While neither party cites any case discussing this question, and our research reveals no controlling Texas case, we are guided by the Supreme Court’s opinion in
Michigan v. Summers,
It is clear that there are several investigative techniques which may be utilized effectively in the course of a Terry -type stop. The most common is interrogation, which may include both a request for identification and inquiry concerning the suspicious conduct of the person detained. Sometimes the officer will communicate with others, either police or private citizens, in an effort to verify the explanation tendered or to confirm the identification or determine whether a person of that identity is otherwise wanted.... There is no reason to conclude that any of the investigative methods of the type just listed are inherently objectionable. ...

Search and Seizure
§ 9.2, pp. 36-37 (1978) (footnotes omitted) (emphasis added). Either through independent analysis or in reliance on this portion of Professor La Fave’s treatise, many jurisdictions have approved warrant checks conducted by the police during otherwise valid investigatory stops.

“Reasonableness” is the standard with which all governmental intrusions on one’s privacy and freedom of physical movement must comply. U.S. Const, amend. IV. In determining what is reasonable, courts must consider the “totality of the circumstances,”
United States v. Cortez,
Robbery Sentence
In his two remaining grounds of error, appellant seeks to have his sentence reduced in the robbery case. According to appellant, the trial court based the sentence on two probation violations that were unsupported by the evidence. We find no merit in appellant’s contentions.
In the original trial of this case, appellant pleaded guilty pursuant to a plea bargain. Under the terms of this agreement, the trial court assessed eight years imprisonment as punishment but suspended imposition of this sentence by placing appellant on probation.
See Teel v. State,
The appellant does not contest that the evidence supported all of the other alleged probation violations. Since only one violation is necessary to revoke probation,
Moore v. State,
The first violation that appellant claims the trial court improperly considered was the aggravated assault which has been fully discussed in the preceding ground of error. The second violation that appellant claims is unsupported by the evidence is also an aggravated assault on a peace officer in an unrelated incident in which appellant allegedly kicked another arresting officer in the head after that officer placed him in his patrol car. Appellant claims that there was no evidence of bodily injury as required under section 22.02 of the Penal Code. The officer did not testify that the blow inflicted physical pain or otherwise injured him. However, we need not decide whether the evidence in the second violation was sufficient to prove bodily injury because the appellant has failed to show that the trial court abused its discretion by not reducing the punishment originally assessed. See Tex.Code- Crim.Proc. art. 42.-12, § 8(a) (Vernon Supp.1985) (authorizing *640 trial court to reduce sentence if in the best interests of society and the probationer).
Nothing in the record reflects that appellant requested a sentence reduction. Further, the trial court imposed the sentence that appellant agreed to in the plea bargain in the event he violated the terms of his probation.

Notes
. Actually, appellant’s argument presents two questions: whether the police detention violated the fourth amendment and, if so, whether the unconstitutionality of the stop would render all subsequent police activities, though themselves permissible, "unlawful" for purposes of Penal Code section 22.02. Because we hold that the investigatory stop did not violate the fourth amendment, we need not decide and express no opinion on the latter question.
