Recently, Saxena et al. (2018) reported the discovery of a possible radio galaxy, J1530+1049 at a redshift of z=5.72. We observed the source with the European Very Long Baseline Interferometry Network at 1.7 GHz. We detected two faint radio features with a separation of ∼ 400 mas. The radio power calculated from the VLA flux density by Saxena et al. (2018), and the projected source size derived from our EVN data place J1530+1049 among the medium-sized symmetric objects (MSOs) which are thought to be young counterparts of radio galaxies (An and Baan 2012). Thus, our finding is consistent with a radio galaxy in an early phase of its evolution as proposed by Saxena et al. (2018).
