We present our radial-velocity data for HD 190228. The measurements were obtained with the ELODIE echelle spectrograph mounted on the 1.93-m telescope at Observatoire de Haute-Provence. A 1100-day periodic low-amplitude radial-velocity signal is detected revealing the presence of a planetary companion with a minimum mass of 5 MJup.
