We present ALMA CO (2-1) observations of the Seyfert 2 galaxy NGC 3281 at ~100 pc spatial resolution. This galaxy was previously known to present a bi-conical ionized gas outflow extending to 2 kpc from the nucleus. The analysis of the CO moment and channel maps, as well as kinematic modelling, reveals two main components in the molecular gas: one rotating in the galaxy plane and another outflowing and extending up to ~1.8-2.6 kpc from the nucleus, partially encasing the ionized component.
