We study the long term spectral evolution by exploiting the capabilities of \\emph{Fermi} and \\emph{Swift} satellites at different phases, which is complemented by the polarization measurement with the CZTI. While the light curve of the GRB in different energy bands show a simple pulse profile, the spectrum shows an unusual evolution. The first phase exhibits a hard-to-soft (HTS) evolution until $\\sim16-20$\\,s, followed by a sudden increase in the spectral peak reaching a few MeV.
