Bengaluru: A school principal was hacked to death Sunday by a six-member gang in front of 20 students, for whom he was holding a special class, police said.

Sixty-year-old Ranganath, the principal of Havanur Public School in suburban Agrahara Dasarahalli, was holding classes for class 10 students when the gang barged into the classroom and hacked him to death, they said.

They later fled in the car in which they came to the school, police said.

One of the gang members was nabbed later from Mahalaxmi Layout area here, based on a tip off.

The man suffered a leg injury when police fired at him after he attacked them. He was later taken to a hospital and treated.

Police suspect a land dispute relating to the school building to be the reason behind the killing.
