AAP leader Sanjay Singh, attacking the Yogi Govt over Kanpur Encounter, said that on March 14, Devendra Mishra wrote a letter to the SSP and told the SSP about the nexus of Gangster Vikas Dubey and SO Vinay Tiwari but no action was taken. He said there are two reasons behind no arrest of Vikas Dubey, ‘Either the Yogi Government is in with Vikas Dubey or is highly incompetent’.
