We have performed optical spectroscopy of Mrk 622 finding that it shows tripled peaked features. These features are separated in velocity showing two components that are blue-shifted and re- shifted with respect to the systemic velocity, and a third component that is right at the systemic velocity. Besides, when analysing their spectra we find that the ratio of the [OIII] to Hβ and [NII] to Hα lay in the locus of AGN for the blue and red-shifted components, while the systemic velocity component lays at the starburst/HII locus. This is interpreted as having a binary AGN that is orbiting a central Starburst.
