Shiromani Akali Dal (SAD) leader Bikram Singh Majithia on Thursday claimed that a Superintendent of Police in Amritsar was seen shaking hands with Narain Singh Chaura, who shot ex-SAD chief Sukhbir Singh Badal, while he was performing 'sewa'. He further criticised Bhagwant Mann-led AAP government and Amritsar Police Commissioner, saying they are trying to hide their "failures".
