We report our findings from near-infrared imaging of the Herbig-Haro object HH124. The outflow driving source is found to be deeply embedded near the symmetry centre of the outflow. This near-infrared source, which we identify with IRAS 06382+1017, is associated with an infrared reflection nebula. The reflection nebula morphology and the spatial distribution of H2 emission in the vicinity of HH124D lead us to propose, as one possibility, the existence of two outflows. An alternative interpretation of the reflection nebula morphology is reflection off a dusty torus situated in the equatorial plane of IRAS 06382+1017. We also report a tentative detection of Brγ emission associated with IRAS 06382+1017. This emission may originate from the circumstellar accretion disc’s boundary layer or from a stellar wind, and indicates that IRAS 06382+1017 is a young, active T Tauri star. The H2 1–0 S(1) emission in HH124 is clumpy, especially in HH124C. The overall spatial distribution of the H2 emission in the different shock fronts is consistent with emission on the wings of bow shocks with a higher shock velocity for HH124C than for HH124E.
