The CBI said it apprehended the Class XI Ryan International School student last night.
The Central Bureau of Investigation on Tuesday made a decision to probe four members of Gurugram Special Investigation Team (SIT) who investigated Pradyuman murder case. After thorough investigation, the CBI detained the boy and claimed that he had murdered Pradyuman to get school exams postponed.
The senior student was not properly questioned or investigated by the police, who focused on the conductor even though both were seen on security footage exiting the toilet around the time Pradyuman was murdered.
"Investigators suspect that after killing the student by slitting his throat, the accused deliberately threw the weapon, a knife which he procured a day before the murder from Sohna, in the commode of the toilet where the incident took place on 8 September", a CBI source had said.
The team, which arrested bus conductor Ashok Kumar and declared him a pedophile, admitted that they made mistakes.
Bus conductor Ashok Kumar was arrested by Gurugram police in connection with Pradyuman's murder.
The CBI is now believed to be probing the angle of cops "planting evidence" in form of blood-soaked knife in Ashok's possession and also torturing the bus driver Saurav Raghav to confess assisting in the crime.
Earlier, the CBI produced the accused, who is a minor, before the JJB and demanded his six-day custody. This is a conspiracy hatched by the school administration and the police. "We're not alleging anything as yet, but we're definitely curious about how investigating officials missed or misinterpreted these", an officer told TOI.
The Juvenile Justice Board had directed CBI to allow child welfare committee (CWC) to probe the social activities of the murder suspect and profile his behaviour, likings and followings on the social front. It said that the 16-year-old accused told the agency that he had known Pradyuman from the piano class they attended together in the school.
The accused student has been sent to Faridabad observation home where he will be kept until the next hearing in the case on November 22.
