Based on the complaint lodged by senior students, Prathipadu SI and his personnel entered the Guntur Engineering College and thrashed nine students inside the classroom. Later, students were shifted to Prathipadu police station. Students in support of arrested students boycotted classes and staged a protest on Chilakaluripet highway. They asked how an SI can enter the educational institution without arrest warrant and permission from the management. Students warned to continue road blockade if the government fails to take taken against SI.
