Amritsar, April 6 -- Union minister of state for railways and food processing industries Ravneet Singh Bittu on Sunday lashed out at the AAP government for not arresting former minister Laljit Singh Bhullar's father and personal assistant in connection with Punjab State Warehousing Corporation officer Gagandeep Singh Randhawa's suicide case.While interacting with mediapersons at the residence of Randhawa here, Bittu said, "The state government ordered an inquiry under the supervision of the chief secretary, but neither the chief secretary nor any other senior officer ever visited the family. We cannot hope for justice in such a situation." Taking on the Punjab Congress president and Ludhiana MP Amarinder Singh Raja Warring, the Union minister said, "Despite appeal of deceased's wife, Warring has not signed the petition seeking a CBI probe." Randhawa, 45, died by suicide on March 21 after recording a 12-second video message in which he reportedly blamed former minister Laljit Singh Bhullar for harassment and intimidation....
