The CBI has apprehended a Class XI student in connection with the killing of a seven-year-old schoolboy in Gurgaon’s Ryan International School, sources have said.

Pradyuman, a class XI student of the school, was found dead with his throat slit by a sharp-edged weapon on the morning of September 8, reported PTI.

The Central Bureau of Investigation will demand custody of the juvenile student, the agency said.

“After a thorough investigation based on scientific evidence including inspection of the scene of crime, forensic analysis and an analysis of CCTV and call records, CBI apprehended the student,” CBI spokesperson Abhishek Dayal was quoted as saying by ANI.

The father of the Class 11 student confirmed his son was detained, but told India Today there was a conspiracy to frame his son. He said his son was the first one to spot the Class 2 boy on the day of the murder, and that the CBI questioned him for an entire day before detaining him.

The prime suspect in the killing was the school bus conductor, Ashok Kumar, the report said. After Kumar’s arrest, the police had said he confessed to the crime, News18 reported.

Kumar is still in judicial custody, The Hindu reported.
