The OPERA long baseline experiment located in the INFN Gran Sasso underground Laboratory was designed to establish the νμ → ντ oscillations in appearance mode, using the CNGS neutrino beam. Five ντ candidate events have been detected in a data sample from the 2008-2012 runs, with a expected background of 0.25 events. The background only hypothesis is rejected with a significance larger than 5σ. The analysis of the tau neutrino sample in the framework of the 3+1 neutrino model is presented. OPERA is able to identify νe CC events due to the good tracking capabilities of its target. The electron neutrino sample is also used to set limits on the 3+1 oscillation parameters.
