The parents of one of the two children, who allegedly shot and killed their classmate, were absconding, even as a case was registered against the father whose gun was used in the murder.

A day after 14-year-old Abhishek Tyagi was killed allegedly by two of his classmates, who pumped five bullets into him shortly after the school closed, the parents of one of the accused children were on the run.

Deputy Commissioner of Police Satish Balan said action would be taken against Azad Yadav, the father of one of the accused children, under the Arms Act for alleged negligence.

Azad's son had brought his licensed revolver to school and allegedly fired four shots at Abhishek near the staircase and then handed the gun to his friend who fired another bullet.

The school situated in Sector 45, was, meanwhile, closed for two days.
