  We investigate the TeV models for neutrino mass generation as candidate
models to explain the recent 2$\sigma$ excess of leptonic $W^{+}W^{-}$ pair
production at LHC. Several models with singly charged exotic states that may
explain the excess require light masses completely excluded by LEP experiments.
One possible model with new lepton doublets can fit the observation and evade
all direct search bounds but with tuned Yukawa structure to satisfy lepton
universality. The new exotic leptons $L^{\pm}$ decay into $L^{\pm}\to
\ell^{\pm} \phi$ where $\phi$ is a light singlet scalar of $\cal O$(MeV) that
decays into neutrinos. Drell-Yan production of $L^{+}L^{-}\to
\ell^{+}\ell^{-}+\cancel{E}_{T}$ fits the excess and $L^{\pm}L^{0}\to
\ell^{\pm}+\cancel{E}_{T}$ is completely buried in SM background.
