  The nearby galaxy HIZSS003 was recently discovered during a blind HI survey
of the zone of avoidance (Henning et al. 2000). Follow up VLA as well as
optical and near-IR imaging and spectroscopy (Massey et al. 2003; Silva et al.
2005) confirm that it is a low metallicity dwarf irregular galaxy. However
there were two puzzling aspects of the observations, (i) current star
formation, as traced by H$\alpha$ emission, is confined to a small region at
the edge of the VLA HI image and (ii) the metallicity of the older RGB stars is
higher than that of the gas in HII region. We present high spatial and velocity
resolution Giant Meterwave Radio Telescope (GMRT) observations that resolve
these puzzles by showing that HIZSS003 is actually a galaxy pair and that the
HII region lies at the center of a much smaller companion galaxy (HIZSS003B) to
the main galaxy (HIZSS003A). The HI emission from these two galaxies overlaps
in projection, but can be separated in velocity space. HIZSS003B has an HI mass
of 2.6 X 10^6 M$_\odot$, and a highly disturbed velocity field. Since the
velocity field is disturbed, an accurate rotation curve cannot be derived,
however, the indicative dynamical mass is ~5 X 10^7 M$_\odot$. For the bigger
galaxy HIZSS003A we derive an HI mass of 1.4 X 10^7 M$_\odot$. The velocity
field of this galaxy is quite regular and from its rotation curve we derive a
total dynamical mass of ~6.5 X 10^8 M$_\odot$.
