  In this work, we present a scotogenic model, where the neutrino mass is
generated at one-loop diagrams. The standard model (SM) is extended by three
singlet Majorana fermions and two inert scalar doublets instead of one doublet
as in the minimal scotogenic model. The model scalar sector includes two
CP-even, two CP-odd and two charged scalars in addition to the Higgs. The dark
matter (DM) candidate could be either the light Majorana fermion (Majorana DM),
or the lightest among the CP-even and the CP-odd scalars (scalar DM). We show
that the model accommodates both Majorana and scalar DM within a significant
viable parameter space, while considering all the relevant theoretical and
experimental constraints such as perturbativity, vacuum stability, unitarity,
the di-photon Higgs decay, electroweak precision tests and lepton flavor
violating constraints. In addition to the collider signatures predicted by the
minimal scotogenic model, our model predicts some novel signatures that can be
probed through some final states such as $8~jets+\slashed{E}_T$,
$1\ell+4~jets+\slashed{E}_T$ and $4b+\slashed{E}_T$.
