    We have detected in ALMA observations CO J = 6 -> 5 emission from the nucleus of the Seyfert galaxy NGC 1068. The low-velocity (up to +/- 70 km s(-1) relative to systemic) CO emission resolves into a 12 x 7 pc structure, roughly aligned with the nuclear radio source. Higher-velocity emission (up to +/- 400 km s(-1)) is consistent with a bipolar outflow in a direction nearly perpendicular (similar or equal to 80 degrees) to the nuclear disk. The position-velocity diagram shows that in addition to the outflow, the velocity field may also contain rotation about the disk axis. These observations provide compelling evidence in support of the disk-wind scenario for the active galactic nucleus obscuring torus.
