The State appeals from the trial court’s grant of Paul Richards’ motion to suppress the statements he made and the evidence found in his truck after an officer approached him while he was sitting in his vehicle at a gas station. The State contends that Richards voluntarily consented to the search of his truck and his person. For the reasons that follow, we reverse and remand with direction.
In reviewing the grant or denial of a motion to suppress, we construe the evidence in a light most favorable to upholding the trial court’s findings and judgment. When the trial court’s findings are based upon conflicting evidence, we will not disturb the lower court’s ruling if there is any evidence to support its findings [.]. . . The trial court’s application of law to undisputed facts, however, is subject to de novo review.

The undisputed evidence adduced at the motion to suppress hearing shows that, around noon on February 13, 2013, Atlanta Police Department Officer Whitfield observed a silver Nissan pickup truck parked at a gas pump at a station located on North Avenue in Fulton County. The location, which is near the Georgia Tech campus, is known for high drug traffic, particularly heroin.
Richards and another man were just sitting in the truck, so Officer Whitfield pulled up beside the driver’s side and began a conversation with them. Both Richards, who was sitting in the driver’s seat, and the passenger stated that they were visiting a friend at Georgia Tech and were on their way home to Dalton.
During the conversation, Officer Whitfield asked Richards and the passenger if either of them used any illegal drugs, and Richards responded that he had used oxycodone in the past and was on probation for drug charges. Officer Whitfield then asked the men if they would mind showing him their arms. When Richards pulled up his sleeves, the officer saw track marks on his arms that did not appear to be fresh.
Meanwhile, two backup officers arrived in a patrol car and a second unmarked vehicle. One officer was in uniform and the other backup officer wore plain clothing, except for an Atlanta Police vest. After the backup officers arrived, Officer Whitfield asked Richards if he had any drugs on his person or in the truck. Richards responded that there was a package of syringes in the truck for the passenger’s diabetic grandmother. The passenger removed the syringes and gave them to Officer Whitfield.
Officer Whitfield then searched Richards’ person, with his consent, and found $250 in Richards’ shirt pocket. When Officer Whitfield asked Richards why he had the money, Richards responded that he was waiting to meet a drug dealer to buy a gram of heroin. Shortly thereafter, one of the backup officers performed a consent search of Richards’ truck and found a small black overnight bag in the rear seat of the truck on the driver’s side. The bag contained a five milliliter bottle of ketamine — a schedule 3 substance used as a horse tranquilizer. Richards initially stated that the black bag belonged to him, but retracted his statement after the ketamine was discovered inside the bag. Richards and the passenger were then placed under arrest, received their Miranda rights and waived them.
Richards subsequently moved to suppress his statements and the evidence found in his truck. Following a hearing, the trial court granted the motion, finding that Richards was subjected to a seizure at the moment Officer Whitfield asked him to roll up his sleeves to *60check his arms for needle track marks. The trial court further found that the mere fact that Richards was stopped at a gas pump at noon in a high drug area and was on probation for drugs did not create the reasonable articulable suspicion necessary to justify the seizure, and that this unlawful seizure tainted Richards’ subsequent consent to the search of his person and vehicle.
1. The State contends that the trial court erred in granting Richards’ motion to suppress by failing to apply the law to the facts of the case. Specifically, the State argues that the trial court erred in finding that Officer Whitfield’s request to see Richards’ arms was a “seizure” which required articulable suspicion that Richards was engaged in criminal activity. We agree.
Our analysis necessarily begins with the Fourth Amendment to the United States Constitution, which provides, inter alia, that the right of the people to be secure in their persons, houses, papers, and effects, against unreasonable searches and seizures, shall not be violated. In construing this amendment, the Supreme Court of the United States has set forth . . . three tiers of police-citizen encounters: (1) communication between police and citizens involving no coercion or detention and therefore without the compass of the Fourth Amendment, (2) brief seizures that must be supported by reasonable suspicion, and (3) full-scale arrests that must be supported by probable cause.

In a first-tier encounter, police may approach citizens, ask for identification, ask for consent to search, and otherwise freely question the citizen without any basis or belief of criminal activity so long as the police do not detain the citizen or convey the message that the citizen may not leave.
(Punctuation and footnote omitted; emphasis in original.) Carter v. State, 319 Ga. App. 624, 625-626 (737 SE2d 724) (2013). “A citizen’s ability to walk away from or otherwise avoid a police officer is the touchstone of a first-tier encounter.” (Citation omitted.) Thomas v. State, 322 Ga. App. 734, 737 (2) (b) (746 SE2d 216) (2013).
A seizure or second-tier encounter “only occurs when, in view of all the circumstances surrounding the incident, a reasonable person believes that he is not free to leave.” (Footnote omitted.) Carter, supra at 625. Here, in order for Officer Whitfield’s request to see Richards’ *61arms to be considered a seizure or second-tier encounter, the officer must have appeared to be asserting some authority, such as giving an order or a command. Thomas, supra. Factors to consider when determining if an officer’s words or conduct are considered a seizure include: (1) whether there were several officers present, creating a threatening atmosphere; (2) whether any weapon was displayed; (3) whether any physical touching occurred; or (4) whether any language or tone of voice indicated that the defendant was compelled to comply with the officer’s request. See State v. Dukes, 279 Ga. App. 247, 249 (630 SE2d 847) (2006). “In the absence of some such evidence, otherwise inoffensive contact between a member of the public and the police cannot, as a matter of law, amount to a seizure of that person.” (Footnote omitted.) Id.
In Dukes, a case involving a charge of obstruction, officers approached Dukes and others outside a convenience store, and one of the officers asked Dukes what he was doing. In response, Dukes said that he was “just sitting around.” The officer asked Dukes if he had identification, and he responded that it was in his vehicle. The officer then asked Dukes if he had any drugs on him and if he would mind emptying his pockets onto the picnic table. Dukes placed the items from his pockets onto the table and then ran from the officers. Id. at 247-248. We held that this interaction was a first-tier encounter because the officer did not seize Dukes, but instead, the officer simply approached and questioned him without effectuating a seizure. Id. at 249.
A similar factual scenario is presented in this case. Here, Officer Whitfield was not threatening nor did he use a show of force, and he did not touch Richards or employ language that would have made Richards believe he was compelled to comply with the request to roll up his sleeves. Specifically, Officer Whitfield testified to the following facts:
I observed a silver Nissan Frontier pickup parked at the gas pump at the [convenience store]. ... I observed that [the men] were just sitting in the car not getting gas, not going in the store. So I. . . pulled up beside the driver [’s] side of the vehicle and began [a] conversation with the occupants.... I explained to the occupants that the area was known for high drug traffic and asked if either of them used any illegal drugs Richards stated that he used oxycodone in the past and [that] he was on probation for drug charges. At that point, I asked both occupants if they would mind showing me their arms. At that point, both occupants did so.
*62The above testimony clearly indicates that Officer Whitfield was simply engaged in a conversation with Richards and the other occupant at the time he asked the men to roll up their sleeves. There was no evidence that the men had been detained at this point. In fact, the record shows that the men were still in their vehicle during this time. A request to search made during the course of a first-tier encounter does not escalate the contact to a second-tier detention. See Carter, supra at 626.
In Brown v. State, 301 Ga.App. 82 (686 SE2d 793) (2009), weheld that a first-tier encounter escalated to a second-tier encounter when the officer directed the defendant to remove his hands from his pockets. Id. at 84. Here, however, Officer Whitfield made no such demand. He merely asked the men if they would mind showing him their arms. This request does not constitute a second-tier encounter. See Carter, supra at 624-626 (first-tier encounter where officer asked defendant if he could retrieve a tool containing knives from the defendant’s pocket and defendant consented); Dukes, supra at 248-249 (first-tier encounter where officer asked defendant if he would mind emptying his pockets and defendant consented).
Blocking a defendant’s path or exit can also escalate a first-tier encounter into a second-tier detention. See In the Interest of J. B., supra at 681 (1). Here, however, the evidence is undisputed that Officer Whitfield pulled alongside Richards’ vehicle and was not blocking his exit. Furthermore, there was no evidence as to when the backup officers arrived or where they parked, and the trial court made no such finding. Rather, the trial court clearly bases its ruling on the erroneous belief that Officer Whitfield’s mere request to see Richards’ arms constituted a seizure. This is not the law.
As the officer’s interaction with Richards at the time of the request did not constitute a second-tier detention, the trial court erred in granting the motion to suppress on this basis.
2. The question of whether the arrival of the backup officers had any effect on Richards’ subsequent consent to the search of his person and vehicle was not addressed by the trial court.
In a consent search, the burden is on the State to demonstrate that the consent was voluntarily given, and not the result of duress or coercion, express or implied. Whether an individual’s consent is, in fact, voluntary, is to be determined from the totality of all the circumstances under which consent was given.
(Punctuation and footnotes omitted.) State v. Baker, 261 Ga. App. 258, 260 (582 SE2d 133) (2003). “As this [C]ourtis limited to resolving *63questions of law rather than fact,” the issue of Richards’ subsequent consent to the search of his person and vehicle must be remanded to the trial court for further consideration. (Punctuation and footnote omitted.) Id.
Accordingly, the trial court’s ruling on the motion to suppress is reversed, and the case is remanded to the trial court to address the issue of whether the presence of the additional officers had any effect on Richards’ subsequent consent to the search of his person and vehicle.
Judgment reversed and case remanded with direction.
