Following earlier searches by the Kamiokande-II Collaboration for neutrino-induced events of special interest, a further intensive search has been made for electron events in the energy interval 6Ee30 MeV, which are clustered in time. No time cluster which might be interpreted as a neutrino burst was found in 2.8 yr of data apart from the burst from SN 1987A. An unusual group of events, not the result of a neutrino interaction in the detector, but clustered in time and space within the detector was observed; information concerning it is presented here.
