Sengupta, who underwent a heart surgery recently, was re-admitted to a city hospital following urine infection and slipped into coma since yesterday, family sources said.
He is survived by wife, a daughter and a son.
Sengupta had worked for Bengali dailies 'Jugantar' and 'Ananda Bazar Patrika' in his long career spanning over six decades.
West Bengal Chief Minister Mamata Banerjee expressed grief at Sengupta's death and remembered his reportage of the 1971 Bangladesh liberation war.
