We report GMRT observation of the strong radio source 4C 35.06, an extended (z = 0.047) radio-loud AGN at the center of galaxy cluster Abell 407. The radio map at 610 MHz reveal a striking, helically twisted jet system emanating from an optically faint AGN host. The radio morhology closely resembles the precessing jets of the galactic microquasar SS433. The optical SDSS images of central region show a complex ensemble of nine galactic condensations within 1arc minute, embedded in a faint, diffuse stellar halo. This system presents a unique case for studying the formation of a giant elliptical galaxy (cD) at the cluster center.
