J113924.74 + 164144.0 is an interesting galaxy at z = 0.0693 , i.e . D _ { L } \sim 305 Mpc , 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 H i 21 cm observations of this field to search for signatures of possible interaction .
Narrow H i emission is detected from J113924.74 + 164144.0 , but J113922.85 + 164136.3 shows no detectable emission .
The total H i mass detected in J113924.74 + 164144.0 is 7.7 \times 10 ^ { 9 } M _ { \odot } .
The H i 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 H i emission from another nearby galaxy J113952.31 + 164531.8 at z = 0.0680 at a projected distance of 600 kpc , and with a total H i mass of 5.3 \times 10 ^ { 9 } M _ { \odot } , suggesting that all these galaxies form a loose group at z \sim 0.069 .
