  We identify a horseshoe-shaped ring (HSR) of diffuse emission in J1407+0453
from the Faint Images of Radio Sky at Twenty-cm (FIRST) survey using the Very
Large Array telescope. An optical galaxy SDSSJ140709.01+045302.1 is present
near the limb of the HSR of J1407+0453, with a spectroscopic redshift of
$z=0.13360$. The total extent of the source, including the diffuse emission of
J1407+0453, is 65 arcsec (with a physical extent of 160 kpc), whereas the
diameter of the HSR is approximately 10 arcsec (25 kpc). The flux density of
HSR is $\sim$47 mJy at 1400 MHz whereas the flux densities of whole diffuse
emission of J1407+0453 at 1400 MHz and 150 MHz are 172 mJy and 763 mJy,
respectively. We measure the radio luminosity of HSR J1407+0453 as 1.94 $\times
10^{24}$ W Hz$^{-1}$ with a spectral index $\alpha_{150}^{1400}=-0.67$. The
black hole mass of J1407+0453 is 5.8$\times10^8$ M$_{\odot}$. We compare the
HSR of diffuse emission of J1407+0453 with other discovered diffused circular
sources. The possible formation scenarios for J1407+0453 are discussed to
understand the nature of the source. We present a spectral index map of
J1407+0453 to study the spectral properties of the source.
