A shocking matter has come to the fore that shows how public life was endangered by a group of goons brandishing weaponry without any fear of authorities or police. Some students in Chennai were seen brandishing long knives on a moving train as well as on the station. As per reports, the students, belonging to the city's Pachayappa College, not only wielded knives but also showed metallic rods and shouted 'Pachayappa' while recklessly brandishing their weapons at Nemilichery railway station. The students also created ruckus after getting out of the train as they showed off their weapons to people and also burst crackers.
