A 16-year-old accused of killing a seven-year-old boy at a private school in Gurugram in September will be tried as an adult, the Gurugram District and Sessions Court said on Monday, The Times of India reported.

Additional Sessions Judge Jasbir Singh Kundu rejected a plea by the juvenile’s family and upheld a Juvenile Justice Board order that the 16-year-old be tried as an adult. The accused’s family had said that the board had approved the trial of the 16-year-old as an adult even before the Central Bureau of Investigation could complete its inquiry and file a chargesheet.

Advocate Sushil Tekriwal, who represents the family of the seven-year-old boy, argued that the juvenile board’s order was “well-reasoned” and there was “nothing illegal” in it, according to PTI.

The seven-year-old boy, a Class 2 student, was found in a school toilet with his throat slit. The 16-year-old student, a Class 11 student at the same school, was detained for the boy’s murder. According to the CBI, he was killed by the 16-year-old, Class 11 student at the same school, to get the school closed so that a parent-teacher meeting and an examination would be deferred.
