Can a search warrant be used to relocate a defendant after he first refused to consent to a search?

Even if the relocation were constitutional, continued detention after defendant's first refusal to consent to a search constituted a custodial interrogation without probable cause under the reasoning of Dunaway and Chamberlin. As such, the government had no justification for conducting a pat-down search thereafter, and the cocaine taken from defendant was thereby tainted by the illegal detention and should have been suppressed.
