Teacher commits suicide after attack by students

A teacher of a private Polytechnic Institute allegedly committed suicide by hanging himself at his house here as he felt "ashamed" after he was beaten up by his students following a wordly duel, police said.
They said the teacher Subramanian scolded 20 of his students for not doing class works and examinations properly.
The inebriated students went to Subramanian's house, took him out in a car and thrashed him. He suffered external injuries in the attack.
