  We consider a general two Higgs doublet model which can simultaneously solve
discrepancies in neutral B meson decay ($b\to s\ell \overline \ell$
distribution) and charged B meson decay ($b\to c\tau\overline\nu$) with a
charged Higgs. The model contains two additional neutral scalars at the same
mass scale and predicts distinctive signals at the LHC. Based on the recent
same-sign top search by the ATLAS collaboration, we found the constraint on the
scalar mass spectrum. To probe the remaining mass window, we propose a novel
$cg\to t\tau\overline\tau$ process at the LHC.
