"As a student/youth activist who often was at the receiving end of the tender mercies of police feel sad and angry at Sudipta Gupta's death," Tewari said in a post on social networking website Twitter.
"Hope the government of W Bengal that consists of former Chattra Parishad/ Youth Congress activists would surmount partisan politics for justice," he added.
22-year-old Sudipta Gupta, who was arrested after a clash with police, died yesterday triggering a row with police who claim Gupta fell from a vehicle, while opposition leaders alleged he had succumbed to injuries sustained in lathicharge by police.
