Varun Thakur, father of Pradyuman Thakur who was murdered inside Ryan International School, on Monday doubted involvement of the top management of the school.
Thakur also said that local administration and people with access to government might be involved to save the real killer.
Earlier on November 8, the CBI said that a class XI student of Ryan International School killed seven-year-old Pradyuman Thakur to postpone school examinations and parent teachers meeting.
In a sensational twist to the case, the agency announced that it had apprehended a senior student of Ryan International School on Tuesday night in connection with the murder of Pradhuman Thakur, rejecting the Gurugram police's theory that the killing was the handiwork of Ashok Kumar.
The CBI has said that there was no evidence against Kumar so far.
Opposition party also attacked the BJP government and Chief Minister Manohar Lal Khattar over the "shoddy" police probe.
Bus conductor Ashok Kumar was arrested by Gurugram police in connection with Pradyuman’s murder.
The Gurgaon Police arrested Ashok in hurry and even Khattar congratulated the team for cracking case the same day.
Gurgaon Police Commissioner Sandeep Khairwar declared in a press meet on September 10 that Ashok was the killer and that he had tried to sexually assault Pradhuman.
