Four 10th standard students were critically injured after they were chased and stabbed outside a school in East Delhi on Saturday.

The incident happened outside Sarvodaya Bal Vidyalaya located in East Delhi’s Mayur Vihar area just when the students were leaving the school premises after giving their 10th standard exam.

Most of the 10th class students witnessed the scene. The victims, identified as Gautam, Rehan, Faizan and Ayush, ran towards a nearby park with the perpetrators fast on their heels, when the four were caught and stabbed.

The four boys are students of Government Boys Senior Secondary School Trilokpuri, and were only at the Sarvodaya Bal Vidyalaya centre for their exams.

Following the attack, the students rushed the four boys to Delhi’s Lal Bahadur Shastri Hospital.

The boys had lost a fair amount of blood by then, witnesses giving the account of the crime said.

The Pandav Nagar police station had received three separate calls about a fight breaking out between two student groups.

When the police reached the scene, the minors were under treatment for serious injuries inflicted upon them, said the District Commissioner of Police (DCP) East.

All the boys wounded in the stabbing were between 15 to 16 years old.

While three boys have been discharged after being treated at Lal Bahadur Shastri hospital, the fourth victim is still under medical treatment in the trauma centre at AIIMS, Delhi, the police added.

Police are scanning the CCTV footage to determine who the perpetrators are.

A further police enquiry has revealed that the attackers are students at R.S. Bal Vidyalaya.
