Appellant stands convicted by a jury on two counts of possessing a controlled substance, heroin and methadone, with the intent to distribute in violation of 21 U.S.C. § 841(a)(1) (1970). 1 Appellant was arrested by agents of the Drug Enforcement Administration (DEA) at Hopkins International Airport in Cleveland, Ohio, while in possession of approximately 330.24 grams of heroin and approximately 475 mililiters of methadone. Appellant raises a number of issues on appeal, the most significant of which are the District Court’s refusal to suppress the seized evidence, failure to consolidate the separate counts of the indictment, and failure to instruct the jury on an essential element of an offense under 21 U.S.C. § 841(a)(1). Although the first two contentions are without merit, we conclude that the failure to instruct the jury on the “intent to distribute” element of § 841(a)(1) requires reversal.
On August 19, 1976, Special Agents William P. Johnson and Frank J. Magoch, Jr., of the DEA were assigned to the Cleveland airport to monitor incoming and outgoing flights to cities known to be drug distribution centers. Agent Johnson observed Appellant among passengers disembarking from a Los Angeles flight. One month earlier, on July 21, Appellant and a companion had aroused Agent Johnson’s suspicions as they boarded a flight to Los Angeles. On that occasion, Agent Johnson observed the two men purchase one-way tickets to *666 Los Angeles using cash taken from large rolls of bills which each was carrying. Appellant had a brown briefcase and his companion carried a brown paper sack from which he removed money to pay his fare. Agent Johnson learned from the ramp agent that the airline tickets were issued in the names of N. Pope and C. Saunders. Agent Johnson made inquiry and obtained a photograph of Saunders, Appellant’s companion. DEA agents maintained surveillance on incoming Los Angeles flights for the next two days but they did not see either of the two men return.
After Agent Johnson noticed Appellant disembark on August 19, he and Agent Magoch followed Appellant down the airport concourse. The evidence shows that the Appellant appeared nervous and looked about several times, glancing at either Agent Johnson or Agent Magoch who were following him. The agents separated, with Agent Magoch continuing to keep Appellant under surveillance while Agent Johnson preceded them outside the terminal and on to the street. Agent Johnson identified himself to a uniformed police officer who was on duty outside the terminal and requested assistance. After Appellant left the terminal, Agent Johnson approached him and displayed his credentials. Immediately, Appellant bolted past the agent and policeman and ran into a nearby construction site. Agent Johnson gave chase shouting after Appellant that he was a federal agent. As Agent Johnson drew closer, Appellant either swung or threw his briefcase at the pursuing agent who then drew his service revolver. Appellant ran toward a storm sewer and, within view of both agents, withdrew a white bag from his coat, dropped down to the sewer grating, and stuffed the bag into the sewer. He was taken into custody and Agent Magoch retrieved a white airsickness bag from the sewer. Inside the airsickness bag were two plastic bags filled with a brown substance which proved to be heroin. Appellant was placed under arrest. The agents opened the briefcase and found that it contained a soft drink bottle filled with a pink liquid which proved to be methadone, a mortar and pestle, an electric blender and a jar of lactose. Appellant had $528 in cash in his pants pockets. Two one-way airline ticket stubs, Los Angeles to Cleveland, in the' names of M. Johnson and J. Johnson, bearing a travel date of August 19, 1976, were in Appellant’s coat pocket. In the briefcase, Agent Johnson found two additional ticket stubs, Los Angeles to Cleveland, in the names of A. Jones and E. Jones dated July 24, 1976. 2
Defense counsel moved to suppress the seized evidence and the motion was overruled. At trial, DEA chemist John Meyers testified that he had analyzed the evidence and found that the brown substance was 330.24 grams of heroin at 23% purity with manitol as dilutant; the surfaces of the mortar and pestle were coated with heroin and manitol; powder in the blender proved positive for heroin; and the pink substance in the bottle was 475 mililiters of liquid containing methadone.
Recently, this Court has reviewed a number of cases involving warrantless searches of airline passengers by DEA agents. See, e.
g., United States v. Lewis,
As we stated in
United States v. McCaleb,
Even if the facts known to the agents do not amount to probable cause, the agents may be permitted to make a limited investigative stop of suspicious individuals under the “stop and frisk” doctrine announced in
Terry
v.
Ohio,
*668
A threshold question we must address is whether the facts before us define an investigative stop within the meaning of
Terry.
Agent Johnson had just approached Appellant and flashed his credentials when Appellant fled.
Terry
states that the Fourth Amendment becomes relevant to an encounter between police and citizen only upon a “seizure of the person”.
Here, Agent Johnson was obviously intending to make a
Terry
stop when he approached Appellant to “talk” with him. This intention was thwarted, however, by Appellant’s flight at the moment the agent displayed his credentials. If the agent had actually succeeded in effecting an investigative stop by detaining Appellant for questioning at the time of the initial intrusion, the stop would have been invalid because the facts then known to the agent did not amount to “reasonable suspicion” that Appellant was involved in criminal activity.
See United States
v.
Cupps,
We conclude that Appellant’s flight in the face of a clear showing of lawful authority supplied the agent with grounds to reasonably suspect that Appellant was engaged in criminal activity. Flight invites pursuit and colors conduct which hitherto has appeared innocent. Under the circumstances, the agent acted reasonably in pursuing Appellant.
5
We wish
*669
to emphasize the narrowness of this holding. We do not condone, nor do we wish to encourage, investigative stops of citizens on a public street on facts which do not meet the standards in
Terry.
All that we hold today is that flight from a clearly identified law enforcement officer may furnish sufficient ground for a limited investigative stop.

See United States v. Vasquez,
Appellant contends that the trial court should have consolidated the separate heroin and methadone counts into a single charge. He was convicted under 21 U.S.C. § 841(aXl) which makes it a crime “for any person knowingly or intentionally to possess with intent to . distribute ... a controlled substance.” Both heroin and methadone are listed as controlled substances in 21 U.S.C. § 812 — heroin is a Schedule I controlled substance and methadone is a Schedule II controlled substance. We conclude that the possession of heroin and methadone represent separate offenses under the provisions of the Comprehensive Drug Abuse and Control Act of 1970, 21 U.S.C. §§ 801
et seq.,
and that the district court did not err in refusing to consolidate the two counts of the indictment into a single charge or in sentencing Appellant separately on each conviction.
Cf. United States v. Valot,
A more serious problem is raised by Appellant’s contention that the district
*670
court improperly instructed the jury on the elements required to prove a violation of 21 U.S.C. § 841(a)(1). Appellant claims that the instructions failed to inform the jury that it must find that controlled substances were possessed “with the intent to distribute” before an offense under § 841(a)(1) is proven. Since Appellant failed to make a specific objection before the jury retired, we review the adequacy of the instructions under the “plain error” standard of Rule 52(b) of the Federal Rules of Criminal Procedure.
See United States v. LaRiche,
Section 841(a)(1) of Title 21 of the United States Code provides in pertinent part as follows:
“Except as authorized by this subchap-ter, it shall be unlawful for any person knowingly or intentionally to manufacture, distribute, dispense, or possess with intent to manufacture, distribute, or dispense a controlled substance.”
I shall now instruct you on the elements of the crime charged in the indictment. The three essential elements of the charges in the indictment are as follows:
1. The act or acts of possessing a narcotic drug controlled substance; to-wit, in this case, heroin, as charged in Count 1 of the indictment, and/or Methadone, as charged in Count 2 of the indictment.
2. Possessing such narcotic drug-controlled substance knowingly and intentionally.
3. Possessing such narcotic drug-controlled substances unlawfully.
The offenses and each of them are complete when the three elements above-stated have been proved by the evidence beyond a reasonable doubt.
A review of this portion of the instruction reveals that the district court did not include “intent to distribute” among the “three essential elements” that the Court said were required to prove a § 841(a)(1) violation. This was error. The “intent to distribute” is an essential element of § 841(a)(1).
See United States v. Clark,
In determining the propriety of a jury instruction, the instruction must be viewed in its entirety, and a misstatement in one part of the charge does not require reversal if elsewhere in the instruction the correct information is conveyed to the jury in a clear and concise manner so that it is unlikely that an erroneous impression would remain in the minds of the jurors.
See generally United States v. Park,
Reversed and remanded.
Notes
. (a) Except as authorized by this subchapter, it shall be unlawful for any person knowingly or intentionally — •
(1) to manufacture, distribute, or dispense, or possess with intent to manufacture, distribute, or dispense, a controlled substance; or
(2) to create, distribute, or dispense, or possess with intent to distribute or dispense, a counterfeit substance.
21 U.S.C. § 841(a)(1), (2) (1970).
. The Government in its brief notes that Appellant returned to Cleveland on July 24th. This date appears to be substantiated by ticket stubs found in Appellant’s briefcase bearing the name “Jones”. Since the agents were not aware of the July 25 flight date and also were not aware that Appellant had used aliases on flights other than on July 21, these facts may not be considered in evaluating the agents’ conduct.
. In
United States v. McCaleb,
*667 The “drug courier profile” is a rather loosely formulated list of characteristics used by Detroit DEA agents to indicate “suspicious” persons. These characteristics include: (1) the use of small denomination currency for ticket purchases; (2) travel to and from major drug import centers, especially for short periods of time; (3) the absence of luggage or use of empty suitcases; (4) nervousness, and; (5) use of an alias. DEA agents testified that the presence of a number of these characteristics suggests that the person observed may be carrying contraband drugs. During the time period of the instant arrests, this profile was not written down, nor was it made clear to agents exactly how many or what combination of the characteristics needed to be present in order to justify an investigative stop or an arrest.
The Cleveland DEA agents followed a similar profile in United States v. Craemer, supra at 595:
The courier profile lists a number of characteristics believed to be common to persons using airports for narcotics traffic. Among the characteristics included in the profile are that the individual purchases a round trip ticket to various locations in the nation known as drug distribution centers, including Miami, Florida, New York, New York, Los Angeles, California, and San Juan, Puerto Rico, to return the same day or within a short period of time; the tickets are purchased with cash using bills of small or large denominations; the individuals either check no luggage or they check empty bags; they often use aliases; and they behave in a suspicious or nervous manner.
. The Government in its brief states that the agents discovered that Appellant’s companion was a “known drug dealer” and that this fact justified the agent’s attempt to stop Appellant outside the terminal. There is nothing in the record to support this allegation. We also did not consider Appellant’s probation report which was improperly inserted as an appendix to the Government’s brief.
. If the agents had apprehended Appellant without further incident, the stop and inquiry would have had to be “reasonably related in scope to the justification for their initiation,” in this case the flight from the agents.

Wong Sun v. United States,
. Simple possession of a controlled substance is a violation of 21 U.S.C. § 844(a) (1970), which carries a maximum term on the first offense of one year imprisonment and a $5000 fine. Compare, 21 U.S.C. § 841(b), (c).
