Steven Andrew Berg appeals his conviction for possession with the intent to distribute more than five kilograms of cocaine, in violation of 21 U.S.C. § 841. He argues that the prosecutor’s closing argument improperly commented on his post-arrest, post-Miranda silence, in violation of Doyle v. Ohio, 426 U.S. 610, 96 S.Ct. 2240, 49 L.Ed.2d 91 (1976), and that the error requires automatic reversal.

A prosecutor violates a defendant’s due process rights by commenting on a *430 defendant’s post-arrest, post-Mmroda warning silence in an attempt to impeach the defendant’s exculpatory testimony offered at trial. Doyle v. Ohio, 426 U.S. 610, 619-20, 96 S.Ct. 2240, 49 L.Ed.2d 91 (1976). Contrary to Berg’s assertion, the prosecutor’s comments regarding his silently “looking straight ahead” reference his silence during secondary inspection, which silence occurred prior to any arrest and thus do not violate Doyle. See United States v. Musquiz, 45 F.3d 927, 930 (5th Cir. 1995).

Berg also objects to the prosecutor’s comment on his failure to say anything after he was arrested and placed in a holding cell. Although the remark referenced Berg’s post-arrest silence, there is no evidence in the record that Berg’s silence at that point was induced by Miranda warnings, a prerequisite for a Doyle violation. See Doyle, 426 U.S. at 619-20, 96 S.Ct. 2240. Even if a Doyle violation is assumed, however, the error was harmless given that the statement was not linked to the exculpatory statement Berg offered at trial, that the trial court sustained Berg’s objection and gave a curative instruction, and that the evidence of Berg’s guilt was overwhelming. See United States v. Rodriguez, 43 F.3d 117, 123 (5th Cir. 1995); United States v. Carter, 953 F.2d 1449, 1466 (5th Cir. 1992); Chapman v. United States, 547 F.2d 1240, 1247-48 (5th Cir. 1977).

The district court’s judgment is AFFIRMED.
