The United States appeals the district court’s suppression of evidence obtained during a search of Walter Jaehimko’s home. We reverse and remand for further consideration.
I. BACKGROUND
In March 1992, Joseph Hendrickson approached the Drug Enforcement Administration (DEA) with information about individuals engaged in indoor marijuana cultivation. He identified Robert Anhalt, Robert’s brother William, and five other individuals as being involved in the operation, but did not know of (and therefore did not divulge) Ja-chimko’s involvement.
The DEA began observing the individuals Hendrickson identified. On March 24, Hen-drickson arranged a meeting between the Anhalts and a DEA undercover agent, with the meeting taking place at Robert’s house. Another meeting took place the next day, at which time undercover agents arranged to purchase some marijuana plants. On June 1, *298 Hendrickson met Robert at Robert’s house, purchased two plants, and ordered 150 more. One week later, Hendrickson paid Robert $150 toward this purchase and arranged to see the plants on June 30. Hendrickson wore a recording device to both of these meetings, and DEA agents monitored the conversations.
On June 30, DEA agents met Hendrickson near Robert’s house and supplied him with a recording device and an agent alert button. He was instructed to activate the alert button only if he saw more than one hundred marijuana plants. Hendrickson then went to Robert’s house, came back, then returned to Robert’s house.
At this point, events took a turn toward the unexpected. Hendrickson and Robert left Robert’s house in a car; the DEA agents followed them. Hendrickson and Robert drove to and entered Jachimko’s house; at the time, the DEA did not have any suspicion that Jaehimko was involved in any drug activity, nor did they suspect that there was marijuana inside the house.
Twenty minutes after entering Jachimko’s house, 1 the agent alert button was activated, and agents knocked on the side door. Ja-chimko opened the door, but tried to close it when the agents identified themselves. A scuffle ensued, and Jaehimko and Robert were arrested. DEA agents searched the premises and seized marijuana plants.
After being indicted for possessing marijuana with intent to distribute, Jaehimko

moved to suppress the marijuana plants seized from his house. In addition to the findings outlined above, the court found “that Hendrickson was not only not a credible witness, but that he in all probability perjured himself before the court.”
United States v. Anhalt,
II. DISCUSSION
“Unless there is an emergency (‘exigent circumstances’), government agents need a warrant to conduct a search of or make an arrest in a person’s home without his consent, even if they have probable cause to believe there is contraband or other incriminating evidence there.”
United States v. Paul,
The concept originated in
United States v. White,
The doctrine was slightly extended in
United States v. Paul,
In the case at bar, the district court committed clear error,
United States v. Spears,
Because the case is to be remanded, we believe it appropriate to address another related issue that has been raised in this case. Jachimko contends he revoked his consent; the government contends that, once granted, Jachimko could not withdraw his consent. The concept of consent once removed is, ultimately, a variation of the “traditional” consent, doctrine; accordingly, because consent may be withdrawn,
United States v. Dyer,
III. CONCLUSION
The district court erred by failing to apply the analytical framework from Diaz to the facts of this case. We therefore vacate the *300 suppression order and remand for further proceedings consistent with this opinion.
Notes
. The record does not disclose what happened during these twenty minutes. The district court observed that Hendrickson's recording device was not working, and the DEA agent who monitored the transmitter did not make a report about what he heard.
. Robert Anhalt pleaded guilty to this charge. The fate of the other individuals Hendrickson identified does not appear in the record.
. It is worth noting, however, that we recently held that an allegedly consensual search may be unreasonable in a given situation.
