Kolkata: Cricket Association of Bengal (CAB) joint secretary Arun Mitra died of a heart attack while on way to his factory.
He was 72 years old and is survived by wife Bithi and only daughter Swagata.
Mitra was known for his close association with the Ganguly family.
According to his nephew Bhaskar Chanda, he died before he could be taken to a private nursing home in Beliaghata.
"I was travelling in the same car when he had the massive attack on the way from his residence to factory in Chingdighata. He succumbed there only, though we took him to the nursing home," his nephew told reporters.
Mitra`s body will be brought to CAB in the evening to pay the last homage, joint secretary Biswarup Dey said.
A strapping 6 feet 4 inches tall, Mitra`s association with Bengal cricket was 32 years oldeven before the Ganguly brothers -- Snehashish and Sourav -- picked up the willow.
Mitra was a close friend of Sourav`s father Chandidas and played a huge role in shaping the career of the most successful Indian captain.
Sourav`s elder brother Snehashish, however, is yet to convey the news to his father who has not been keeping well.
"He will be deeply sad... I am yet to tell him," the elder Ganguly told reporters.
Remembering his contribution to Bengal cricket, Snehashish said, "For more than three decades he has served Bengal cricket.
"I remember of seeing him when as a kid, I used to go to CAB holding dad`s hands. He was so affable among us. His contribution to Bengal cricket is immense," he said.
Away in Delhi, Sourav, however could not be contacted.
Mitra, who represented Belgachia United, has held several posts in CAB including team manager, selection committee chairman and was elected uncontested for a third term as joint-secretary.
