OPINION
Federal drug enforcement agents arrested defendants-appellees David Lopez-Arias and Antonio Egues for trafficking in cocaine. After a federal grand jury indicted them, defendants moved to suppress certain evidence, alleging that it was obtained as a result of an unlawful arrest. The district court granted defendants’ motion to suppress, and the government appeals from that ruling. For the following reasons, we affirm the district court’s decision to suppress the evidence.
I.
On or shortly before July 26, 2000, law enforcement officials in Louisville, Kentucky, received a tip from a confidential informant, whose reliability had not yet been tested, that two Hispanic men from Las Vegas were traveling to Louisville to distribute cocaine. The informant told the police that the two men intended to stay at the Collier Motel in Louisville and that a man named Jose intended to deliver the proceeds of a drug sale to these two men at the motel. According to the informant, Jose would be driving a white Toyota with a certain license plate number. A search of state motor vehicle records revealed that the license plate number identified by the informant was registered to Jose Barrera Santiesteban, 104 E. Kingston, Apt. 1, Louisville, Kentucky.
The federal Drug Enforcement Administration (DEA) began surveillance of the Collier Motel on the afternoon of July 26, 2000. During their surveillance, DEA agents discovered that a 1992 blue Ford Crown Victoria, which was parked in front of Room 17 of the motel, was registered to David Lopez-Arias, whose address matched Santiesteban’s except for the apartment number. At around 4:00 p.m. on July 26, defendants Lopez-Arias and Egues exited Room 17 and departed in the Crown Victoria. The undercover DEA *626 agents followed defendants as they visited several locations, including an office supply store, where they purchased a set of digital scales of the type often used to weigh drugs. Defendants then returned to the motel.
At around 8:15 that evening, Santieste-ban arrived at the motel driving the white Toyota described by the informant. After speaking with Lopez-Arias, who was outside working on the Crown Victoria, San-tiesteban went into Room 17 with Lopez-Arias. DEA agents observed Santieste-ban carrying a yellow plastic bag into Room 17. Santiesteban stayed in Room 17 for about forty-five minutes before leaving in his white Toyota. DEA agents followed Santiesteban out of the vicinity of the motel and then stopped him. A drug-sniffing dog alerted on the Toyota, but the DEA agents did not find any drugs in the Toyota.
Defendants departed from the motel in the Crown Victoria shortly after Santieste-ban and were followed by DEA agents. Once the drug-sniffing dog alerted on San-tiesteban’s Toyota, a DEA agent on the scene with Santiesteban ordered the DEA agents following defendants to stop the Crown Victoria. Four DEA agents in four unmarked DEA vehicles activated their sirens and emergency lights and stopped the Crown Victoria. The four DEA agents, with weapons drawn, ordered defendants to exit the Crown Victoria. The DEA agents then handcuffed defendants and placed them into separate DEA vehicles. The DEA agents drove the' defendants from the scene of the stop on the street to an adjacent convenience store parking lot, where they were removed from the DEA vehicles, read their Miranda rights, and questioned separately.
The DEA agent questioning Egues conducted a pat-down search of him and found the motel key in his pocket. Egues stated that the motel room was registered in his name. The DEA agent asked Egues for consent to search the motel room and presented him with a written consent form, which Egues signed within ten to fifteen minutes from the time the DEA agents stopped the Crown Victoria. A little more than twenty minutes from the time the DEA agents stopped the Crown Victoria, Lopez-Arias gave the DEA agent questioning him verbal consent to search the motel room.
After receiving consent from both defendants, DEA agents searched Room 17 of the Collier Motel and found a yellow plastic bag containing twenty-five individually wrapped packages of cocaine, a black notebook containing $4,100 in cash, clear plastic wrappers containing cocaine residue, and two sets of digital scales. DEA agents then formally arrested defendants and reread them their Miranda rights.
The federal grand jury charged defendants with possessing more than 500 grams of cocaine with the intent to distribute. Before trial, defendants moved to suppress all the evidence that the DEA agents found in the motel room. Defendants argued that they were arrested without probable cause and that they did not voluntarily grant consent to search the motel room. The district court referred defendants’ motion to a magistrate judge, who conducted an evidentiary hearing. The magistrate judge issued proposed findings of fact and conclusions of law and recommended that the motion to suppress be denied. The magistrate judge found that defendants voluntarily gave their consent to search the motel room during a permissible investigatory detention that had not yet risen to the level of an arrest.
Defendants objected, and the district court rejected the magistrate judge’s recommendation and granted defendants’ motion to suppress. The district court found *627 that the stop had risen to the level of an arrest by the time defendants gave their consent to search the motel room, that no probable cause existed to support the arrest, and that the consent was therefore tainted by the illegal arrest. Because the district court found that the consent was tainted by the illegal arrest, the district court did not decide whether the consent was otherwise voluntary. The government appeals the district court’s ruling to suppress the evidence found in the motel room.
II.
“This Court reviews the district court’s factual findings in a suppression hearing for clear error and reviews the district court’s conclusions of law de novo.”
United States v. Waldon,
A The Seizure
The government does not argue that the DEA agents had probable cause to arrest defendants at the time defendants granted their consent to search the motel room. The government instead argues that defendants gave their consent to search the motel room during a permissible investigatory detention that had not yet risen to the level of an arrest.
Since the Supreme Court decided
Terry v. Ohio,
To determine whether an investigative detention has crossed the line and become an arrest, this court considers factors such as “the transportation of the detainee to another location, significant restraints on the detainee’s freedom of movement involving physical confinement or other coercion preventing the detainee from leaving police custody, and the use of weapons or bodily force.”
United States v. Richardson,
But there is no bright line that distinguishes an investigative detention from an arrest.
Royer,
In the present case, the district court did not clearly err in finding that before defendants gave their consent to search the motel room, they were (1) stopped by four DEA agents brandishing firearms, (2) handcuffed, (3) placed into the backseats of separate DEA vehicles, (4) transported from the scene of the stop, (5) read their
Miranda
rights, and (6) questioned. The government, relying on
Houston,
argues that all these measures were reasonably necessary for the protection of the DEA agents. The seizure in the present case, however, was more like an arrest than the seizure this court considered in
Houston.
In addition to taking the same protective measures as did the police officers in
Houston,
the DEA agents in the present case transported defendants from the scene of the stop and read them their
Miranda
rights. Each of these additional measures made the seizure more like an arrest.
See Heath,
Moreover, in this case, defendants were not suspected of anything so dangerous as shooting a police officer, as was the case in
Houston.
In this ease, defendants were suspected of possessing illegal drugs, just as were the defendants in
Heath, Butler,
and
Richardson.
The seizure in this case was at least as intrusive as the seizures that this court determined were arrests in
Heath, Butler,
and
Richardson. Heath,
B. The Consent
The government argues that, even if defendants’ consent to search the motel room was granted during an unlawful arrest, the district court nevertheless erred in suppressing the evidence found in the motel room because defendants’ consent to search, according to the government, was voluntary. For this argument, the government primarily relies upon
United States v. Guimond,
It is without a doubt true that “[t]he Fourth Amendment test for a valid consent to search is that the consent be voluntary.”
Robinette,
Therefore, following Supreme Court precedent, we have repeatedly held that if a consent to search is given after an illegal seizure, evidence obtained pursuant to the consent to search must be suppressed, unless the consent is sufficiently attenuated from the illegal seizure such that the consent is the product of an intervening act of free will.
United States v. Caicedo,
*630
To determine whether a consent to search was sufficiently attenuated from an illegal seizure such that the causal chain was broken, courts must consider factors such as the length of time between the illegal seizure and the consent, the presence of intervening circumstances, the purpose and flagrancy of the official misconduct, and whether the officers read the suspect his
Miranda
rights before he consented.
Kaupp,
— U.S. at -,
In
Brown,
the Supreme Court held that a separation of less than two hours between an illegal arrest and a voluntary statement was insufficient to break the causal chain between the two when no intervening event of significance had occurred.
III.
For all the foregoing reasons, we affirm the district court’s ruling to suppress the evidence discovered in the motel room.
Notes
. In
Guimond,
a panel of this court seemingly held that if the consent to search was voluntary, it does not matter that the consent occurred during an illegal seizure.
