Gurugram police on Tuesday said that they have finished questioning of the bus conductor accused of killing seven-year-old Pradymna Thakur at Ryan International School and they don't see involvement of more persons in the crime.

"The questioning of bus conductor Ashok is complete and his remand has ended. He told us whatever we needed to know. We are satisfied with the information," Birem Singh, ACP Sohna Road told reporters.

"It is clear that only Ashok is involved in the murder of the seven-year-old," Singh said.

He, however, made it clear the 'act of negligence' by the school is a separate matter, which is also being probed.

"Only Ashok has murdered Pradyumna, no other person involved in the murder. Act of negligence by the school is a separate matter and two people are being questioned for the same," ACP Singh said.

He said that two children disclosed the accused bus conductor was present in the toilet before the incident.

The ACP said they will 'try their best' to file chargesheet in court by Saturday. -- ANI
