  We report optical observations of TGSS J1054+5832, a candidate high-redshift
($z=4.8\pm2$) steep-spectrum radio galaxy, in $r$ and $i$ bands using the faint
object spectrograph and camera mounted on 3.6-m Devasthal Optical Telescope
(DOT). The source previously detected at 150 MHz from Giant Meterwave Radio
Telescope and at 1420 MHz from Very Large Array has a known counterpart in
near-infrared bands with $K$-band magnitude of AB 22. The source is detected in
$i$-band with AB$24.3\pm0.2$ magnitude in the DOT images presented here. The
source remains undetected in the $r$-band image at a 2.5$\sigma$ depth of AB
24.4 mag over an $1.2''\times1.2''$ aperture. An upper limit to $i-K$ color is
estimated to be $\sim$2.3, suggesting youthfulness of the galaxy with active
star formation. These observations highlight the importance and potential of
the 3.6-m DOT for detections of faint galaxies.
