The facts, as determined by the lower court, are that on 19 April 1991, Officers J.M. Ferrell and J.A. Gunn were at the Amtrak railroad station in High Point patrolling as part of a drug interdiction operation. At 1:30 a.m., the officers observed the defendant, *810Mary Alice Pittman, and a man speaking. Upon noticing that they were being watched by the two officers, defendant and the man parted company. Officer Gunn stopped the defendant, and Officer Ferrell stopped the man with whom defendant was seen. The two were stopped approximately twenty feet apart. Defendant showed Officer Gunn a train ticket bearing the name A. Reynolds and stated that she was travelling alone and did not know the man with whom she had been seen. During the conversation, Officer Gunn noticed the defendant was constantly looking over at the man and Officer Ferrell. Defendant consented to a search of her bag. No drugs or contraband were discovered by the search. Meanwhile, Officer Ferrell spoke with the man who had been observed with the defendant. The man claimed to be travelling alone and said he did not know the defendant. The man consented to a search of his bag, and this search was also negative.
After Officer Ferrell ended his conversation with the man, a Honda automobile pulled up to the train station, and the man put his bag in the trunk. The man then motioned to the defendant to approach the car and he placed her bag in the trunk and the two of them got in the car and left. Officers Gunn and Ferrell compared the information they had gathered from the defendant and the man, noting particularly that both said they were travelling alone and did not know the other. When the officers observed the two leaving in the same car, their suspicions were aroused. Officers Gunn and Ferrell followed the car and had a uniformed police car stop the Honda. Before speaking to the defendant a second time, a call was made for a female officer to go to the scene. Officer Gunn asked the defendant to get out of the car and asked her why she had misrepresented that she was travelling alone as well as several other questions. The officers requested to search the defendant, and she refused. The female officer, Sherry Byrum, had arrived and was instructed to conduct a search of defendant’s person. Because of the hour, defendant was taken to the police station where the search was conducted in the ladies public rest room. The search uncovered two bags of cocaine:
The issue on appeal is whether the lower court committed prejudicial error by denying the defendant’s motion to suppress evidence seized in violation of the defendant’s rights as guaranteed by the United States Constitution, the North Carolina Constitution, and N.C. Gen. Stat. § 15A-974. Defendant makes three contentions in support of her appeal.
*811First, defendant claims that the initial encounter between herself and the police at the train station was a seizure without reasonable suspicion. Recently, the United States Supreme Court has reiterated that police officers may approach individuals in public places “to ask them questions and to request consent to search their luggage, so long as a reasonable person would understand that he or she could refuse to cooperate.” Florida v. Bostick, 501 U.S. —, —, 115 L. Ed. 2d 389, 396 (1991). The Court further explains that “a seizure does not occur simply because a police officer approaches an individual and asks a few questions.” Id. at —, 115 L. Ed. 2d at 398. Such encounters are considered consensual by the Court and no reasonable suspicion is necessary. Id. This Court has found that “[communications between police and citizens involving no coercion or detention are outside the scope of the fourth amendment.” State v. Thomas, 81 N.C. App. 200, 205, 343 S.E.2d 588, 591, disc. review denied, 318 N.C. 287, 347 S.E.2d 469 (1986) (quoting State v. Perkerol, 77 N.C. App. 292, 298, 335 S.E.2d 60, 64 (1985), disc. review denied, 315 N.C. 595, 341 S.E.2d 36 (1986)). In the case sub judice, defendant was approached by only one clearly identified police officer at the train station who merely asked her a few questions. Defendant voluntarily gave Officer Gunn her train ticket and consented to the search of her bag. Because of the consensual nature of the encounter, defendant’s argument that this encounter constituted a seizure is without merit.
The second contention defendant makes is that the stop of the car in which defendant was a passenger was an arrest without probable cause. In support, defendant asserts that because she had already been questioned once, there was no other investigative work to be done; therefore, the second stop was an arrest. The State asserts that defendant lacks standing to challenge the stop of the vehicle. However, the State is precluded from raising the argument of lack of standing on appeal because it failed to raise lack of standing to defeat the Fourth Amendment claim at the suppression hearing in the lower court. State v. Cooke, 306 N.C. 132, 138, 291 S.E.2d 618, 621-22 (1982).
This Court has found that “[i]t is well-settled law that a police officer may make a brief investigative stop of a vehicle if justified by specific, articulable facts giving rise to reasonable suspicion of illegal activity.” State v. Reid, 104 N.C. App. 334, 342, 410 S.E.2d 67, 71 (1991), disc. review allowed, 331 N.C. 121, 414 S.E.2d 765 (1992). Reasonable suspicion is determined by the totality of the *812circumstances. Reid, 104 N.C. App. at 342, 410 S.E.2d at 72, (quoting Alabama v. White, 496 U.S. 325, 110 L. Ed. 2d 301 (1990)). The existence of reasonable suspicion of criminal activity is determined by trained police officers from objective facts and circumstantial evidence. State v. McDaniels, 103 N.C. App. 175, 180, 405 S.E.2d 358, 361, disc. review on additional issues denied, 329 N.C. 791, 408 S.E.2d 527 (1991), decision aff’d, 331 N.C. 112, 413 S.E.2d 799 (1992). By the standards set out by the Supreme Court and this Court, the stop of the car in which defendant was a passenger was not an arrest. The police were making an investigative stop of the vehicle to clarify the discrepancies between defendant’s story and her actions. The specific articulable facts that were the basis of the officers’ reasonable suspicion of illegal activity were: (1) defendant was observed in a public transportation area where controlled substances are commonly trafficked; (2) upon questioning, defendant had claimed she was travelling alone; (3) she claimed she did not know the man to whom she had been speaking; (4) she constantly looked over at the man being questioned by Officer Ferrell, and (5) subsequently, she left with that very man in a car. These specific, articulable facts justified the subsequent stop of the vehicle.
So long as a stop is investigative, the police only need to have a reasonable suspicion. Reid, supra. However, if the police conduct a full search of an individual without a warrant or consent, they must have probable cause, and there must be exigent circumstances. State v. Mills, 104 N.C. App. 724, 730, 411 S.E.2d 193, 196 (1991). Whether there were exigent circumstances need not be considered because probable cause to search did not exist. The United States Supreme Court compared the difference between investigative stops and situations which required probable cause in Florida v. Royer, 460 U.S. 491, 75 L. Ed. 2d 229 (1983).
Detentions may be “investigative” yet violative of the Fourth Amendment absent probable cause. In the name of investigating a person who is no more than suspected of criminal activity, the police may not carry out a full search of the person or of his automobile or other effects. Nor may the police seek to verify their suspicions by means that approach the conditions of arrest.
Id. at 499, 75 L. Ed. 2d at 237.
*813This Court has determined that probable cause to search exists when a “reasonable person acting in good faith could reasonably believe that a search of the defendant would reveal the controlled substances sought which would aid in his conviction.” Mills, 104 N.C. App. at 730, 411 S.E.2d at 196. At the time Officer Ferrell called for a female officer to conduct a search and subsequently ordered the defendant to submit to a search, there was no probable cause to search, at best only reasonable suspicion. Terry v. Ohio, 392 U.S. 1, 19, 20 L. Ed. 2d 889, 904 (1968), limited the scope of searches so that they are strictly tied to the factors which give rise to the search. In this case, the officer acted on what seemed to be an attempt by the defendant to deny knowing the man with whom she left. A reasonable person could not reasonably believe that a full body search, based on this one factor, would reveal controlled substances, therefore no probable cause existed. Ybarra v. Illinois, 444 U.S. 85, 91, 62 L. Ed. 2d 238, 245 (1979) (“[A] person’s mere propinquity to others independently suspected of criminal activity does not, without more, give rise to probable cause to search that person.”); See also Sibron v. New York, 392 U.S. 40, 62, 20 L. Ed. 2d 917, 934 (1968) (finding that the inference of criminal activity based on mere association with known drug addicts is not sufficient for a finding of probable cause to search).
The State asserts that the police had probable cause to search the defendant based on information gathered from the questioning of the defendant during the second stop. However, Officer Ferrell called for a female officer specifically to conduct a search of the defendant, and he did so before the second stop and further questioning of the defendant began. When the decision to search the defendant was made, the police were working from the limited information gathered from the first stop, and at that point there was no probable cause. Assuming arguendo that the decision to search was made subsequent to the second stop, we also find insufficient evidence of probable cause to permit a search of the defendant’s person.
Lastly, defendant contends that three of the lower court’s findings of fact are not supported by the record. Defendant failed to properly preserve for review by this Court these remaining assignments of error. N.C.R. App. P. 10(b) (1975).
For the reasons stated above, we conclude that the search of the defendant’s person was conducted in violation of the right *814of the defendant to be free from any unreasonable searches as guaranteed by the Fourth Amendment, the North Carolina Constitution, and the North Carolina General Statutes. Accordingly, the order denying defendant’s motion to suppress is reversed and the judgment entered upon defendant’s plea of guilty is vacated.
