We obtained optical and infrared spectra of Cha Hα 5/cc 1, a faint possibly sub-stellar companion candidate next to the M6-type brown dwarf candidate Cha Hα 5 in Cha I, using FORS1 and ISAAC at the VLT. The VRIJHK colors of Cha Hα 5/cc 1 are consistent with either an L-type companion or a K-type background giant. Our spectra show that the companion candidate actually is a background star.
