The police on Wednesday stepped up the investigation into the attack on a woman student inside the Indian Institute of Technology (IIT) campus, with a Special Investigation Team (SIT) launching a detailed inquiry.
The SIT, led by M. Sujit, Inspector of Kasaba police station, has begun examining surveillance footage from various parts of the campus.
The police also conducted a search for the weapon used in the assault, suspecting that the assailant may have discarded it somewhere within the premises after the incident.
The attack occurred on Monday night when Aswini Kannan, a fourth-year BTech Data Science student from Salem, Tamil Nadu, was walking from her hostel to the mess along with friends.
She was trailing behind the group when a man, reportedly wearing a blue shirt, struck her on the head with a wooden plank.
