We present radio observations and modelling of a Type Ib supernova (SN) Master OT J120451.50+265946.6 exploded in the galaxy NGC 4080 at a distance of ~ 15 MPc. The radio light curves and spectra are modelled with the synchrotron emission emanating due to the SN ejecta interacting with the  circumstellar medium created by a wind due to the mass loss from the progenitor star. The low frequency Giant Metrewave Radio Telescope (GMRT) Observations  in the optically thick phase reveal inhomogeneities in the structure of the radio emitting region. The GMRT observations combined with the Karl G. Jansky Very Large Array data indicate that the radio emitting shock is passing through a dense shell during early epochs. Our observations and analysis reveal the importance of obtaining well sampled low frequency data in order to understand the intricate nature of the radio emission from young core-collapse supernovae.
