P Amrish (23) of Madurai, S Saran (23) of Dharmapuri, A Mukesh (21) and R Aban (23) were studying medicine in a private college near Periyapalayam. They were returning to their accommodation near Ponneri after visiting a friend in Red Hills late on Friday night.

Preliminary investigations revealed that Mukesh drove the car. He allegedly lost control of the vehicle while approaching the Karanodai flyover, and the vehicle overturned, leading to the instant death of Amrish and Saran.

Passersby alerted the authorities, after which personnel from the Red Hills Traffic Investigation Wing (TIW) rushed to the scene.

Mukesh and Aban were rescued and shifted to the hospital. The bodies were sent to the Government Stanley Medical College Hospital for post-mortem. The police have registered a case and launched an investigation into the circumstances surrounding the accident.
