In the context of the S-PLUS Fornax Project (S+FP), we recover a population of blue elliptical galaxies in the Fornax cluster, making use of S-PLUS multi-wavelengths data. From the colour magnitude diagram we selected blue objects and visually inspect the correspondent gri images obtained using Legacy data. Studying morfological parameters of these galaxies we find that some of them are classified as irregular and might be merger remnants. Interestingly, they seem to have fallen in the cluster at early ages.
