We have obtained simultaneous multiband photometric and polarimetric light curves for ST LMi (CW1103 + 254) in the visible range and the near-infrared on three occasions. These clearly show the presence of previously unobserved accretion at or near the second magnetic pole of the white dwarf. The secondary accretion region is seen only in the H and J bands, from which we infer a lower accretion rate than for the primary region.
