Mumbai: A thirteen-year-old Gajendra Dubey called up his mother after he finished writing a paper at his Andheri school. He felt ill and could not wait for half an hour for his school bus to arrive. Little did his parents know that it wasn't just examination fever or tiredness. Gajendra, who was part of the boxing team at Andheri's St Xavier's School, died at Sion Hospital due to cardiac shock.
