A charge sheet in the murder of the seven-year-old schoolboy inside Ryan International School in Gurugram will be submitted in court by the Central Bureau of Investigation after it takes charge of the case, the Police said today.

Gurugram Police said it has prepared the charge sheet in the case in which bus conductor Ashok Kumar is the only accused in the murder of the Class 2 student inside the school's toilet on the morning of September 8, but the Special Investigation Team will not file it in court.

The report will be handed over to the CBI once it takes over the investigation within a couple of weeks, police said.

Although Gurugram Police chief Sandeep Khirwar remained tight-lipped on the matter but chief PRO and ACP Manish Sehgal said that now the police has nothing to do with the case.

"The charge sheet will be now submitted by CBI as the case has been recommended by Haryana Chief Minister Manohar Lal Khattar to CBI for the probe," Sehgal told PTI.

However, the family members of the victim Pradyuman and his father Varun Thakur were not satisfied with the theory of 14 teams of SIT of police and demanded a CBI inquiry alleging destruction of key evidence by the school management.

The family members also questioned the 'callous and brazen' attitude of the police when a dog squad was pressed into service at their residence to ensure foolproof security just before the CM's visit on Friday.

"The same police have failed to use a dog squad even a week after my only son's murder inside the school. Maybe it could have produced vital clues and helped the police arrest the accused without any delay since the very first day," Thakur said.  -- PTI
