  We present the HI 21 cm spectral line and continuum observations of the
Galactic supernova remnant candidate G351.7-1.2 using the upgraded Giant
Metrewave Radio Telescope. Strong absorption features are observed towards the
HII regions in the star forming complex associated with G351.7-1.2. Along with
HI emission towards the outer periphery of the supernova remnant shell, we
distinguish a high velocity jet-like feature in the velocity range +40 km/s to
+52 km/s in HI. This unusual and highly collimated feature, with a projected
length of ~7 pc and an opening angle of 14.4 deg, is located towards the
interior of the radio shell. This is the first report of a such a well
collimated HI jet-like emission. The peculiar location and the detection of a
gamma-ray source towards the central peak of this HI jet suggests its plausible
association with the supernova remnant candidate.
