We have observed surprisingly huge dielectric response in a nominally semiconducting quasi one-dimensional system (NbSe4)3I below structural phase transition at 274 K. While the relaxation time shows activated increase on cooling almost following the increase of dc resistivity, the dielectric constant goes through a maximum at 150 K. We discuss the results in the view of charge reordering at 274 K.
