We report the detection of heavy reddening and the He i* \lambda 10830 absorption lines at the AGNs ’ redshift in three Narrow-line Seyfert 1 galaxies : SDSS J091848.61+211717.0 , SDSS J111354.66+124439.0 , and SDSS J122749.13+321458.9 . They exhibit very red optical to near-infrared colors , narrow Balmer/Paschen broad emission lines and He i* \lambda 10830 absorption lines . The ultraviolet-optical-infrared nucleus continua are reddened by the SMC extinction law of E ( B - V ) \sim 0.74 , 1.17 , and 1.24 mag for three objects , which are highly consistent with the values obtained from the broad-line Balmer decrements , but larger than those of narrow emission lines . The reddening analysis suggests the extinction dust simultaneously obscure the accretion disk , the broad emission line region , and the hot dust from the inner edge of the torus . It is possible that the dust obscuring the AGN structures are the dusty torus itself . Furthermore , the Cloudy analysis of the He i* \lambda 10830 absorption lines propose the distance of the absorption materials to be the extend scale of the torus . That greatly increases probabilities of the obscure and absorption materials being the dusty torus .
