### Description

We present our results of tau neutrino events analysis at the Iron Calorimeter (ICAL) detector in India-based Neutrino Observatory (INO). We calculate the tau neutrino interaction with the detector via charged current(CC) interaction over background neutral current (NC) events of neutrinos of all flavors. We find that the presence of tau neutrinos with 10 years exposure at ICAL can be detected with nearly 4 sigma confidence. We show that the tau neutrino events are sensitive to the neutrino oscillation parameters $\theta_{23}$ and $\Delta m^2$. By performing combined analysis of tau neutrino events and muon neutrino events, we show the significant improvement in oscillation parameter $\theta_{23}$ and its octant measurement and moderate improvement in $\Delta m^2$ measurement.
