  We analyse the signatures at the Large Hadron Collider (LHC) of the
scotogenic model, when the lightest Z2-odd particle is a singlet fermion and a
feebly interacting massive particle (FIMP). We further assume that the singlet
fermion constitutes the dark matter and that it is produced in the early
Universe via the freeze-in mechanism. The small couplings required to reproduce
the observed dark matter abundance translate into decay-lengths for the
next-to-lightest Z2-odd particle which can be macroscopic, potentially leading
to spectacular signatures at the LHC. We characterize the possible signals of
the model according to the spectrum of the Z2-odd particles and we derive, for
each of the cases, bounds on the parameters of the model from current searches.
