An engineering student of Nova Engineering College allegedly committed suicide in Vijayawada late on Saturday night.

22-year-old Puvvala Prem Prasad, a fourth-year student of Electrical and Electronics Engineering, ended his life by hanging himself in his hostel room. He did not leave any suicide note.

Pavan Prasad, brother of Prem, said that only two days back he was with his brother and he seemed very friendly.

"We don't know what had happened in college or the hostel. We all are in a shock. He was a very hard working boy who aimed for a huge success in life," he said.

Earlier, three female students of Svs Medical College of Yoga and Naturopathy and Research Institute had committed suicide in Tamil Nadu due to lack of basic infrastructure in the institute.

These incidents came to light after Rohith Vemula, a Dalit scholar of Hyderabad University, allegedly committed suicide after he and his four friends were suspended by the authorities from the hostel after a fight with the ABVP activists in the campus.

The Hyderabad incident had sparked nationwide outrage with the opposition demanding the resignations of Union Ministers Smriti Irani and Bandaru Dattatreya.
