KALAMASSERY: SFI district president Prajith Babu was arrested by the Kalamasery police on Saturday night and released on bail in connection with the attack on M Soman, a security employee at CUSAT. The action was taken on the complaint of the CUSAT registrar. Soman was injured in the attack on Diwali when a group of SFI activists led by Prajith Babu attacked him when he tried to stop them from jumping the wall of the university administrative office building. Even though his arm was broken, Soman did not file a complaint with the police. Two men wearing helmets on bikes had threatened to kill Soman, who is also an ex-serviceman, asking him not to give his statement. On the fifth day after the incident, Cusat officials filed a complaint with the police and their statement was recorded.
