In our study we are searching for imprints of gas accretion onto galaxies residing in voids. The void environment is favorable for distinguishing between different sources of accreted gas. The accretion events could lead to drop of metallicity in certain regions, kinematical perturbations and star formation on the periphery of galaxies. We compiled a sample of void galaxies with intermediate luminosities that reveals unusual and perturbed appearance, some of them also have relatively low metallicity for their luminosity in comparison with standard relation. To examine the hypothesis of gas accretion onto these galaxies we use Fabry-Perot interferometer data in Hα line along with spectral data obtained with 6m SAO RAS telescope (Russia) and deep optical photometry performed with 2.5m telescope of SAI MSU (Russia) together with data available in different surveys. Here we present our results for NGC 428 - the central member of loose group residing in the Eridanus void.
