"We will definitely recommend CBI probe... We can see shortcomings in the ongoing probe. Divyansh's parents levelled serious allegation," said Delhi Deputy Chief Minister Manish Sisodia, who also holds the education portfolio.
The boy's father, Ramheet Meena, had alleged yesterday that there were visible injuries on his son's body, including the child's private parts. He had also reiterated his demand for a CBI probe and cancellation of the school's license.
"I saw the body. There were some injury marks and cotton (swabs) on his private parts. The principal has been threatening me since the beginning, saying keeping quiet will be good for me," he said.
A senior police officer handling the probe, however, had ruled out sexual assault on the basis of the initial post- mortem report and investigation so far.
Mr Meena, who met a Delhi minister said he told the minister that the police wasn't co-operating and did not take the investigation towards the right direction.
"The minister told me that he will meet the Chief Minister (Arvind Kejriwal) at 4 pm and discuss the matter," he told NDTV.
Divyansh was found dead in the reservoir under the amphitheatre of the school located in South Delhi, on January 30. The initial postmortem report suggested he had drowned and there were no external injuries on his body, police had said.
Mr Sisodia had said yesterday the probe indicated a "heinous crime" and the investigation so far has "ignored" the observations of the child's parents. No police officer, he said, has met the parents of Divyansh so far.
