  We report the latest results on the search for the QCD critical point in the
QCD phase diagram through high energy heavy-ion collisions. The measurements
discussed are based on the higher moments of the net-proton multiplicity
distributions in heavy-ion collisions. A non-monotonic variation in the product
of kurtosis times the variance of the net-proton distribution is observed as a
function of the collision energy with 3$\sigma$ significance. We also discuss
the results of the thermal model in explaining the measured particle yield
ratios in heavy-ion collisions and comparison of the different variants of
hardon resonance gas model calculation to the data on higher moments of
net-proton distributions. We end with a note that the upcoming programs in high
baryon density regime at various experimental facilities will complete the
search for the QCD critical point through heavy-ion collisions.
