We here report an identification of SDSS J090152.04+624342.6 as a new overlapping-trough iron low-ionization broad absorption line quasar at redshift of $zsim2.1$. No strong variation of the broad absorption lines can be revealed through the two spectra taken by the Sloan Digital Sky Survey with a time interval of $sim6$yr. Further optical and infrared spectroscopic study on this object is suggested.
