Udhaya Kumar, a college dropout, had killed a 20-year-old engineering student in a classroom.
The police said that they were in a relationship but she stopped talking to him after he left college.
Udhaya Kumar had allegedly stalked Sonali, a third year student, at the engineering college in the Karur district around 400 km from Chennai.
On Tuesday, when he confronted her in the college canteen, she refused to talk to him.
The police say Udhaya Kumar was drunk. He allegedly followed her to class and suddenly attacked her with a log, as her classmates watched in horror.
“She collapsed when she entered the classroom, bleeding,” said senior police officer TK Rajasekaran.
Sonali died in hospital.
Udhaya Kumar tried to run away but was arrested and charged with murder.
The incident comes two months after 24-year-old Infosys techie Swathi was hacked to death at a busy railway station in Chennai by a man she had rejected.
