A ten-member group of students, who picketed the Higher Secondary Directorate Office as part of their agitation, poured engine oil on Director Kesavendrakumar without any provocation after a brief meeting in his office, police said.
A complaint in this regard has been lodged by the Director and based on that, action would be taken against guilty students, police said.
The students also tried to intimidate the employees who attempted to evict the agitating students from the office room, police added.
