It's a parent's worst nightmare come true. A class 8 student at the Euro International School in Guragon, on the outskirts of Delhi, was shot dead by two of his classmates after school hours on Tuesday. Abhishek Tyagi was found dead in his school corridor with 3 bullets in his body. At 2 pm (IST), a bus driver heard gunshots and raced to find a 13-year-old he often brought to school, lying in a pool of blood.
