Chandigarh, June 12 -- Three days after a brawl broke out at Gate Number 2 of Panjab University, a case of rioting and criminal intimidation was registered on Wednesday. A video purportedly showing youths attacking each other with weapons had gone viral on social media. As per preliminary investigation, the brawl had broken out, on the night of June 8, due to a road rage incident. Police officials privy to the matter said, complainant Abhimanyu Sandhu was in his Fortuner car, bearing a Punjab registration number, near Ankur School around 10 pm. The other group, in a car with a Haryana number plate, allegedly took offence that Sandhu didn't give them way, leading to the brawl. PU security officials confirmed that Sandhu is a former student of PU. The identities of the accused are yet to be ascertained. The incident has again brought focus on the security situation at PU. Even as PU claims that entry of outsiders isn't allowed, it couldn't explain how outsiders were able to enter the campus that night and get into a road rage incident. PU is conducting an inquiry into the two security guards who were present at the spot and were seen in the video. PU chief of university security Vikram Singh said with new initiatives, such as entry only to vehicles with stickers, to be rolled out from the start of the next session, it is likely to put a stop to such incidents....
