We search for observational evidence for a second inner planetesimal ring in the system. We obtained total intensity and polarimetric data in the broad bands J and H and processed the data with differential imaging techniques achieving an angular resolution of about 40 mas. We observe an axisymmetric planetesimal belt with a radius of $\\sim$2$''$, an inclination of $85.8^{\\circ} \\pm 0.7^{\\circ}$ and position angle of 278.9$^{\\circ} \\pm 0.1^{\\circ}$.
