We present a simple extension of the standard model (SM) to explain thediphoton excess, reported by CMS and ATLAS at CERN LHC. The SM is extended by adark sector including a vector-like lepton doublet and a singlet of zeroelectromagnetic charge, which are odd under a $Z_2$ symmetry. These vector-likeleptons assist the additional scalar, different from SM Higgs, to decay todi-photons of invariant mass around 750 GeV and thus explaining the excessobserved at LHC. The admixture of neutral component of the vector-like leptondoublet and singlet constitute the dark matter component of the Universe. Weshow the relevant parameter space for correct relic density and directdetection of dark matter.
