  We present high angular resolution observations of OH maser emission towards
the high-mass star forming region IRAS 06056+2131. The observations were
carried out using the UK radio interferometer array, Multi-Element Radio Linked
Interferometer Network (MERLIN) in the OH main lines at 1665- and 1667-MHz, in
addition to the OH satellite line at 1720-MHz. The results of this study
revealed emission in the 1665 MHz line with an estimated total intensity of
$\sim 4$ Jy. We did not detect any emission from the 1667-MHz and 1720-MHz
lines.
  The full polarization mode of MERLIN enables us to investigate the magnetic
field in the OH maser region. Our results show that IRAS 06056+2131 is a highly
circularly polarized source. In this transition, a Zeeman pair is identified
from which a magnetic strength of $\sim -1.5$ mG is inferred. The orientation
of the linear polarization vectors suggests that the magnetic field lines at
the location of the OH maser emission \textbf{might be} in agreement with the
orientation of the outflow thought to be associated with this source. The star
forming evolutionary status of the embedded proto-stellar object is discussed.
