Tiwari and beat in-charge of Bikru KK Sharma, who were suspended soon after the encounter, have also been arrested on charges of fleeing the encounter site and putting the lives of other policemen in danger, Senior Superintendent of Police (Kanpur) Dinesh Kumar Prabhu said.
Both the suspended sub-inspectors were detained for questioning and later arrested, he said.
A separate FIR has been registered at the Chaubeypur police station against Tiwari and Sharma for allegedly fleeing the encounter site, a police spokesperson said.
Both the SIs allegedly tipped off Dubey, a dreaded gangster, about the impending police raid, he added.
Tiwari is said to have been grilled by sleuths from the Uttar Pradesh Special Task Force (STF).
3 alleged accomplices of gangster Vikas Dubey held in Faridabad
Earlier, the Haryana police arrested three alleged accomplices of Dubey in a raid at a house in Faridabad after a tip-off that the gangster was holed up there, officials said on Wednesday.
CCTV footage of a person resembling the gangster trying to book a room at a hotel in Faridabad on Tuesday night went viral. However, the man managed to flee before the police reached there.
According to an FIR lodged in Faridabad, on a tip off that Vikas Dubey and Kartikey were hiding in a house in New Indira Nagar complex in Haripur of Kheri Pul area, a team of Faridabad Crime Branch surrounded a house on Tuesday midnight.
When the police team asked the residents of the house to open the door, one person ran towards the roof and opened fire while two in the house tried to stop the team from entering, it stated.
Later, the three people were nabbed and were identified as Kartikey, Shravan and his son Ankur who gave shelter.
Though the FIR mentioned that there was information about presence of Vikas Dubey in the house, it did not clarify whether the gangster was actually present there or not.
Asked whether the person in the CCTV footage was Vikas Dubey or not, Uttar Pradesh Police’s ADG (Law and Order) Prashant Kumar said, “It’s a matter of probe.”
Of the four pistols seized from the three arrested men, two belong to policemen slain in Kanpur. The three men have been booked under relevant sections of the Indian Penal Code, including including 212 (harbouring offender) and 307 (attempt to murder).
Encounters in connection with the deadly Kanpur ambush also took place Hamirpur, and Kanpur district’s Chaubepur on Tuesday night and Wednesday morning.
Eight Uttar Pradesh Police personnel, including a deputy superintendent of police, were killed and seven others injured in a firefight with criminals in Kanpur on the intervening night of July 2 and July 3.
