  We point out that the excess of electron-like neutrino events recently
observed by the T2K collaboration may have a common origin with the similar
excess events previously reported by the LSND and MiniBooNE experiments and
interpreted as a signal from the radiative decays of a sterile neutrino \nu_h
with the mass around 50 MeV produced in muon neutrino neutral current (NC)
interactions. In this work we assumed that the \nu_h can also be produced in
tau neutrino NC reactions.
