The headmaster of a government-aided school in Thirpuathur was allegedly stabbed by a Class 11 student of the institution Monday after the former questioned him regarding studies, police said.
The student immediately fled the scene and is since absconding.
Headmaster Babu had asked the students of the particular section to come down near his office and study after their teacher for the period was not available.
However, he later discovered that five students, including the alleged attacker had not come and thus he questioned them over the same.
Babu sustained injuries in his stomach and is undergoing medical treatment at a private hospital.
Further probe is underway.
