 On July 17, 2023, a student committed suicide by jumping off the eighth floor of a building on the university campus. The deceased was later identified as Aditya Prabhu, a 19-year old Bachelor of Technology student of the university. The incident occurred after he was allegedly caught using a mobile phone during an examination. Aditya was escorted out of the examination hall at around 11:30 am (IST). He was counselled by the college authorities and informed that his parents would be notified. Distressed, he left the room and jumped to his death some time between 12:30 and 1:00 pm. Aditya's parents then proceeded to file a police complaint against the university management holding them responsible for his death. Aditya's mother alleged through social media that Aditya told her he was being harassed by the college faculty who told him that "it’s better to die than to do such things". The university also caught flak for leaked screenshots from a college group where a member of the administration was seen encouraging students to support the university by countering backlash with positive posts about the university. 
 In response, the university released a statement refuting the charges of harassment and against their policy on malpractice during examinations. Expressing regret, the statement claimed that Aditya was escorted for carrying a mobile phone with material related to the examination and that he was counselled to stay calm and would be given the opportunity to explain his side of the story before he left the room. It went on to refute "all charges that are being made regarding the process and all the lies that are being circulated by opinions on our staff and the welfare of our students". Three members of the faculty, who were present with Aditya were later charged with abetting suicide.
