J113924.74+164144.0 is an interesting galaxy at z = 0.0693, i.e. D_L ∼ 305Mpc, with tidal-tail-like extended optical features on both sides. There are two neighbouring galaxies, a spiral galaxy J113922.85+164136.3 which has a strikingly similar `tidal' morphology and a faint galaxy J113923.58+164129.9. We report HI 21-cm observations of this field to search for signatures of possible interaction. Narrow HI emission is detected from J113924.74+164144.0, but J113922.85+164136.3 shows no detectable emission. The total HI mass detected in J113924.74+164144.0 is 7.7x10⁹M_☉. The HI emission from the galaxy is found to be extended and significantly offset from the optical position of the galaxy. We interpret this as signature of possible interaction with the neighbouring spiral galaxy. There is also a possible detection of HI emission from another nearby galaxy J113952.31+164531.8 at z = 0.0680 at a projected distance of 600kpc, and with a total HI mass of 5.3x10⁹M_☉, suggesting that all these galaxies form a loose group at z ∼ 0.069.
