Tributes have poured in for Board of Control for Cricket in India (BCCI) president Jagmohan Dalmiya from all quarters, after news of the 75-year-old's death in Kolkata came in last night.

According to Dr Anil Mishra, who was treating Dalmiya at the BM Birla Heart Research Insititute, the veteran cricket administrator died of a "massive gastrointestinal hemorrhage" at 8.45pm on Sunday, 20 September.

It was on Thursday night that Dalmiya complained of chest pains and breathing problems, and was rushed to the hospital. 

"He [Dalmiya] was responding to treatment but became unstable in the morning. Our medical board decided to conduct an angioplasty late afternoon. He was stabilised but after that there was a massive gastrointestinal hemorrhage which led to a lot of bleeding," Dr Mishra said in his official medical bulletin last night.

"He succumbed to the bleeding at 8.45pm". 

West Bengal chief minister Mamata Banerjee confirmed Dalmiya will be given state honours during his funeral at the Keoratala crematorium in Kolkata on Monday.

"Dalmiya's contribution to cricket cannot be described in words. It is really shocking to realise that he is no more. I had talked to his family members when he was hospitalised on Thursday. They told me he was doing fine," Banerjee, who rushed to the hospital immediately, told media persons.

"He was like a victorious king who fought valiantly in the field of cricket administration and today he left us but remained undefeated. He had so many dreams about world cup cricket. We will try to fulfil those dreams," she said as a host of former cricketers and officials of the Cricket Association of Bengal (CAB) rushed to pay their last respects.

"He was an asset... we are all proud of him. We will give him state honours," said the chief minister.

Present, former cricketers, politicians and commentators took to twitter to condole the death of Dalmiya, with BCCI secretary Anurag Thakur describing the 75-year-old as the "greatest sports administrator of India".
