After the LEP 3 sigma anomaly in the Zbb coupling, another 2-3 sigma anomaly in the forward-backward top-antitop asymmetry was found at Tevatron. Up to now, on the other hand, there has been no hints of issues with the 3rd generation at the LHC. This latter has discarded many of the models trying to justify the LEP & Tevatron anomalies. In this work we address the case of a warped extra dimension model which could justify the LEP & Tevatron deviations and still be hard to detect at the LHC. We found some interesting regions in parameter space in this model in which pair-production of new particles is phase-spaced-suppressed and therefore coupling-suppressed single-production should be sought. We present a search strategy for the upcoming LHC Run II in which this model could be tested.
