The cop was admitted to a pyschiatric ward soon after he was declared mentally unstable. But two senior officers of the IB ruled out the possibility of mental Mishra's illness in the report they sent to the Centre on Nov 6.
A CBI enquiry into the case has been demanded by Shivpal Singh Yadav, opposition SP and Kalraj Mishra, BJP Vice President who alleged that the family of the top cop lived in fear.
"Mishra was thrashed and almost abducted by the police," said Yadav.
Mishra on Friday had said that his superiors and officials in the UP government were involved in illegal activities.
"Mishra was always ostracised because of his honesty. Three of his batchmates became IGs. But he wasn't promoted," said Yadav.
He also said, "We were present when Mishra was holding the press conference. We were shocked to see the Lucknow police's behaviour. He was almost dragged out of his office for speaking the truth. There can be no justification for such an act."
Meanwhile, the state government said that Mishra suffered from depression due to some family problem.
"It is true he used to get angry at corruption. But his family life was normal," said a subordinate DIG.
Pallavi, the daughter of Mishra said that her father "Was tensed for the last one month because of some unknown reason".
"We were only trying to help him" and that Mishra had broken service rules by publicly speaking against the government. "Whatever he was doing was against rules. Such behaviour is not expected of an IPS officer. He is currently under the observation of doctors for bipolar affective disorder," said Fateh Bahadur Singh, UP Home Secretary.
"Those who are trying to criticise us are anti- social. The state government is against any kind of corruption. An inquiry has been ordered against those whom Mishra charged with financial irregularities," said Swamy Prasad Maurya, BJP State President.
Fateh Bahadur also said that Mishra's family "Had told us his behaviour was not good and he was in depression".
"I know Mishra since his posting in Chitrakoot. He believed in community policing. We considered him a competent officer. But the government dislikes honesty.It appears the system is collapsing," said Ex- DGP Prakash Singh adding that the society should raise its voice.
