"The father even asked the school authorities to hand him over to the police if took the law into his hands. We thought it better to oust him from the school and rusticated him on January 30", she said.
Guard Subhash said, "I was on the gate and he suddenly came and fired at me without saying anything and then went into the school." The school students hid themselves in awe when they saw a pistol in his hand.
