We present the HI 21 cm spectral line and continuum observations of theGalactic supernova remnant candidate G351.7-1.2 using the upgraded GiantMetrewave Radio Telescope. Strong absorption features are observed towards theHII regions in the star forming complex associated with G351.7-1.2. Along withHI emission towards the outer periphery of the supernova remnant shell, wedistinguish 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 projectedlength of ~7 pc and an opening angle of 14.4 deg, is located towards theinterior of the radio shell. This is the first report of a such a wellcollimated HI jet-like emission. The peculiar location and the detection of agamma-ray source towards the central peak of this HI jet suggests its plausibleassociation with the supernova remnant candidate.
