This case presents the question of whether a United States Customs Service agent can detain someone for driving recklessly on the highway. We hold that a Customs agent enjoys the right of citizen’s arrest if the erratic driving occurs in his presence and constitutes a breach of the peace under state law. Accordingly, we affirm the district court’s denial of the motion to exclude incriminating evidence obtained as a result of the valid citizen’s arrest.

Richard 0. Rivera (“Rivera”), a senior special agent at the Falcon Heights, Texas office of the United States Customs Service, left work at around 9:00 PM. Driving an unmarked government-owned Jeep Cherokee, he headed home towards Laredo. Rivera considered himself “off-duty” because his work shift for the day had ended. He was wearing civilian clothes at the time.
Thirty minutes into his trip back home, Rivera observed a pickup truck exit off-a ranch road and turn north onto Highway 83, a two-lane road with one lane in either direction. After several miles, the pickup truck passed Rivera’s car and began driving erratically. Over the course of the next seven or eight minutes, Rivera saw the truck repeatedly cross the center stripe, veer back into the proper lane, and then drive onto the emergency shoulder. At one point, the pickup truck swerved entirely into the wrong lane and flashed its high-beam lights at an oncoming car. -In response, the oncoming vehicle flashed its high-beam lights, blinding Rivera.
Although Rivera’s official duties as a Customs agent do not include the enforcement of traffic laws, he decided to stop the pickup truck for his own safety as well as that of other drivers on the highway. Using the radio in his car, he gave his location and informed the Customs Service of his plan to stop the pickup truck. Rivera’s unmarked government car did not come equipped with red-and-blue emergency lights, but it had headlights capable of a strobe light effect and an audio siren. He turned on both the strobe lights and the audio siren. The driver of the truck responded by accelerating to approximately 85-miles-per-hour. Rivera contacted Customs Service again to request the assistance of the Laredo Police Department. The chase ended when the pickup truck turned right onto a dead-end street. The driver of the pickup truck was a juvenile female (“Sealed Juvenile Defendant”). A search of the bed of the pickup truck revealed over 323 kilograms (711 pounds) of cocaine. The parties stipulate that the cocaine was the defendant’s, and that she had intended to distribute it.
The Sealed Juvenile Defendant was charged with intent to distribute cocaine in violation of 21 U.S.C. § 841(a)(1) and § 841(b)(1)(A). She filed a motion to suppress the evidence of cocaine, alleging that Rivera’s pursuit and detainment of her constituted an unconstitutional arrest under the Fourth Amendment. The district court initially granted the motion to suppress on the ground that he lacked reasonable suspicion to stop the car. It rejected the government’s contention that Rivera, as an off-duty Customs agent, acted as a private citizen. The court said that his use of the flashing headlights, the audio siren, and the radio in a government-owned car clothed his actions with the mantle of government authority.
*216 The government offered several alternative arguments in its motion for reconsideration. After full briefing by both sides, the district court reconsidered its prior decision and granted the government’s motion, thus denying the Sealed Juvenile Defendant’s motion to suppress the evidence. The court maintained that Rivera was a government actor, but it held that Rivera’s stopping of the pickup truck met constitutional muster. While Customs agents are not considered peace officers under Texas law, the district court said that they nevertheless have the right, under Texas’ citizen’s arrest statute, to stop anyone they see committing a felony or breaching the peace. The court opined that the erratic driving constituted an offense against the public peace. Alternatively, Rivera had a reasonable suspicion that the Sealed Juvenile Defendant was driving while intoxicated, which undeniably violates the public peace. The Sealed Juvenile Defendant appeals from the district court’s grant of the motion for reconsideration.
II
This court reviews de novo whether a search or seizure was reasonable under the Fourth Amendment, see
United, States v. Jones,
A
As a preliminary matter, we must briefly discuss whether Rivera’s pursuit and detainment of the Sealed Juvenile Defendant implicates the Fourth Amendment. The United States Constitution’s prohibition against unconstitutional search and seizure applies only to government agents.
See United States v. Paige,
In both the original suppression hearing and in the motion for reconsideration, the government claimed (unsuccessfully) that Rivera had acted as a private citizen. On appeal, the government has abandoned this line of argument. We therefore assume that Rivera acted in his official capacity as a government agent for purposes of the Fourth Amendment. See id. at 1018 (noting that we are “constrained” by a party’s decision not to raise a Fourth Amendment argument on appeal).
B
The next question we address is whether any federal or state law empowered Rivera to stop and detain the Sealed Juvenile defendant. A law enforcement officer can make a warrantless arrest only if a federal or state law imbues him with that authority.
See generally Atwater v. City of Lago Vista,
*217
Given this lack of federal authority, the government must point to a Texas statute giving a Customs agent the power to arrest in this situation.
See United States v. Garcia,
The Sealed Juvenile Defendant responds that a Customs agent does not enjoy the power of citizen’s arrest, despite the plain language of the statute. See Tex.Code Crim. Proc. Ann. art. 14.01(a) (giving the power to a “peace officer or any other person ”) (emphasis added). According to her, the citizen’s arrest statute must be read in conjunction with Tex.Code Crim. Proc. Ann., art. 2.122(a), which states that Customs agents, along with several other listed federal law enforcement agents, are not considered peace officers. In essence, she argues that the right of citizen’s arrest is divested from a federal law enforcement officer acting in his official government capacity. We disagree.
Precedents in both our Circuit as well as in Texas state courts indicate that a Customs agent retains the power of citizen’s arrest, even when he acts in his capacity as a government agent. In
Sanchez v. State,
We similarly have held that “although Military Police [like Customs agents] are not designated peace officers ... they can make an arrest when Texas law authorizes such an arrest by a ‘private person.’ ”
United States v. Mullin,
*218
Indeed, it would be counter-intuitive to deny the right of citizen’s arrest to a citizen who happens to be a federal law enforcement officer. If we adopted the Sealed Juvenile Defendant’s reading of the statute, it would lead to absurd results: a federal agent who witnesses a felony or a breach of the peace would remain helpless to stop the offender, but a private citizen without any law enforcement background could pursue a fleeing felon.
Cf. State v. Gustke,
C
We finally reach the question of whether Rivera’s arrest of the Sealed Juvenile Defendant conformed with the requirements of the citizen’s arrest statute. See Tex. Code Crim. Proc. ANN. art. 14.01(a) (requiring the arresting person to have witnessed a felony or a breach of the peace). The district court found that the Sealed Juvenile Defendant’s erratic driving constituted a breach of the peace.
Texas courts have said the term “breach of the peace” is “generic, and includes all violations of the public peace or order, or decorum.... Accordingly, where means which cause disquiet and disorder, and which threaten danger and disaster to the community are used, it amounts to a breach of the peace, although no actual personal violence is employed.”
Ruiz v. State,
Traffic offenses
per se
do not qualify as a breach of the peace under Texas law.
See Perkins v. State,
Texas courts have found a breach of the peace in situations where the defendant’s actions were arguably less dangerous and noxious to the public.
See, e.g., Crowley v. State,
D
The Sealed Juvenile Defendant makes an alternative argument that Rivera did not intend to “arrest” her when he stopped the pickup truck, because he per
*219
sonally did not suspect, let alone have probable cause for, any criminal activity. Instead, she argues that Rivera only made a
Terry
investigative stop, pointing to Rivera’s testimony that he merely wanted to stop and investigate if there was something wrong with the driver.
See Terry v. Ohio,
This argument fails for two reasons. First, although Rivera mentioned that he stopped the pickup truck in part to investigate if there was something wrong with the driver, he also implicitly justified his decision on the breach of the public peace grounds when he testified that the “vehicle had become a hazard[] on the highway.” Second, even if Rivera had intended to make only a
Terry
investigatory detention, his subjective rationale for stopping the pickup truck does not invalidate the detainment as long as there existed an objective probable cause for arresting the Sealed Juvenile Defendant. Simply put, we look beyond the mere subjective sentiment of the arresting officer or person in determining the legality of an arrest or a search.
See United States v. Gray,
In
Gray,
the police officer testified that he personally did not believe that he had probable cause to conduct a search, but the court found the search to be legal because there was an objective basis for probable cause to search.
See Gray,
III
We hold today that a United States Customs Service agent can invoke the power of citizen’s arrest if he witnesses someone driving erratically and recklessly on the highway. We emphasize, however, that a Customs agent cannot detain someone who merely violates any traffic law. The traffic violation must threaten danger and disaster to the community, thereby breaching the public peace.
AFFIRMED.
Notes
. To the extent that Texas law does not allow private citizens to make
Terry
investigative stops, we disagree with the district court's analysis that Rivera could have stopped the pickup truck on the alternative ground that he reasonably suspected that the driver was intoxicated. Erratic driving in itself does not amount to probable cause for driving under the influence; it only gives an officer an artic-ulable reasonable suspicion to make an investigatory stop.
See Yeager v. State,
