KK Sharma, a sub-inspector (SI) with the Uttar Pradesh police has moved the Supreme Court seeking protection for his wife and himself.

Attached to the Bikru police station Sharma was arrested by the Special Task Force (STF) in connection with allegations that he may have tipped off slain gangster Vikas Dubey's gang about the police raid in Kanpur on July 2.

In his petition to the apex court, SI KK Sharma has claimed that he fears for himself and his wife Vinita Sirohi since he believes that they could also be gunned down in an encounter by the STF like Dubey and his aides.

The cop accused of giving away information that led to the death of eight policemen in the ambush that night, Sharma has appealed to the SC to allow an independent agency or the CBI to probe the allegations against him since it would amount to a free, fair and lawful trial.

"Extra-judicial killings/encounters of other accused in the present FIR shows volumes of the conduct of the police department of State of Uttar Pradesh," KK Sharma said in his petition.

Apart from Sharma, Chaubeypur station house in-charge (SHO) Vinay Tewari is also in police custody. Top officials reportedly uncovered evidence suggesting Tewari may have also tipped off Vikas Dubey.

In his statement, one of the policemen who survived the ambush set up by Vikas Dubey and his aides said that the goons had armed themselves, set up a JCB in front of the gangster's home to block the passage and even used flood-lights to their advantage. Undergoing treatment at a private hospital in Kanpur, Bithoor SO Kaushalendra Pratap Singh had told media outlets the police team that went to arrest Vikas Dubey walked into a massacre because the gangster had been alerted about the raid beforehand.
