Recent study of gamma rays originating from the region of galactic centre hasconfirmed an anomalous $\gamma$-ray excess within the energy range 1-3 GeV.This can be explained as the consequence of pair annihilation of a 31-40 GeVdark matter into $b \bar b$ with thermal annihilation cross-section $\sigma v\sim 1.4-2.0 \times 10^{-26}~\rm{cm^3/s}$. In this work we revisit the InertDoublet Model (IDM) in order to explain this gamma ray excess. Taking thelightest inert particle (LIP) as a stable DM candidate we show that a 31-40 GeVdark matter derived from IDM will fail to satisfy experimental limits on darkmatter direct detection cross-section obtained from ongoing direct detectionexperiments and is also inconsistent with LHC findings. We show that a singletextended inert doublet model can easily explain the reported $\gamma$-rayexcess which is as well in agreement with Higgs search results at LHC and otherobserved results like DM relic density and direct detection constraints.
