The Central Bureau of Investigation on Thursday told a Gurugram court that it had not yet given a clean chit to Ashok Kumar, the bus conductor initially arrested for the murder of a Ryan International School student, ANI reported, quoting the lawyer for the boy’s family.

Kumar had filed a bail application after the CBI absolved him of the murder charge on November 8, and arrested a Class 11 student of the same school. However, on Thursday, the CBI opposed his bail plea, saying since the investigation was ongoing, Kumar cannot be given a clean chit. The court adjourned the hearing of Kumar’s bail plea till November 20.

“So far no incriminating details have been found in CBI investigation in connection with involvement of Ashok Kumar,” the CBI said in Gurugram court. “In case any evidence comes forth during ongoing investigation by the CBI, action will be taken.”

The investigating agency further alleged that the Haryana Police had beaten up Kumar and a key witness in the case – the school gardener – to admit to committing the crime, India Today reported. The court watched the CCTV footage of the crime scene where the Class 11 student is seen entering the washroom where the victim was killed.

Earlier in the day, the court had asked the CBI the basis of Kumar’s arrest, and asked the investigating agency to file a detailed reply by 2 pm, Mohit Verma, the bus conductor’s lawyer had told ANI.

The Class 2 student was found with his throat slit inside the toilet of the school on September 8. An autopsy revealed that injuries on the boy’s neck, inflicted by a sharp-edged weapon, were the cause of death. Kumar was arrested later that day.
