We present the results of Giant Metrewave Radio Telescope ( GMRT ) observations of the interacting system Arp86 in both neutral atomic hydrogen , H i , and in radio continuum at 240 , 606 and 1394 MHz .
In addition to H i emission from the two dominant galaxies , NGC7752 and NGC7753 , these observations show a complex distribution of H i tails and bridges due to tidal interactions .
The regions of highest column density appear related to the recent sites of intense star formation .
H i column densities \sim 1 - 1.5 \times 10 ^ { 21 } cm ^ { -2 } have been detected in the tidal bridge which is bright in Spitzer image as well .
We also detect H i emission from the galaxy 2MASX J23470758+2926531 , which is shown to be a part of this system .
We discuss the possibility that this could be a tidal dwarf galaxy .
The radio continuum observations show evidence of a non-thermal bridge between NGC7752 and NGC7753 , and a radio source in the nuclear region of NGC7753 consistent with it having a LINER nucleus .
