Pakistan coach Bob Woolmer died after being rushed to hospital in Jamaica.
Woolmer was last seen in public when he addressed the post-match press conference after Pakistan’s shock defeat to Ireland.
Officials had apparently been worried after they didn’t see Woolmer early on Sunday.
When they went to his room, they found him unconscious lying on the floor of his room with vomit around him.
Thereafter, the 58-year-old former English player was rushed to the Kingston University Hospital, where he was in emergency care before he passed away.
The news was confirmed by Pakistan team media manager Pervez Mir. "I have to say with great sadness that Woolmer has died. The doctors in the ICU have pronounced him dead," Mir said.
In his last public appearance before his death, Woolmer had apologised to the fans for the World Cup debacle, making no excuses for Pakistan's loss to Ireland, which knocked them out of the World Cup.
Reacting to the news, controversial Pakistani paceman Shoaib Akhtar, who had many run-ins with Bob Woolmer in recent years, expressed utter shock and denied that his relationship with the coach was strained.
"It is a huge loss and we will miss him," said Akhtar.
Meanwhile, former England captain Mike Gatting expressed his sorrow at Woolmer's sudden demise.
"Woolmer was a fine, charming man. He had done wonders with the South African team and was a great innovator of the game," said Gatting.
Woolmer had a history of health problems and was suffering from diabetes.
According to reports, he was bleeding from the nose when he was found and there is a possibility that he could have suffered a hemorrhage.
The Pakistan Cricket Board (PCB) is expected to release a statement later on Sunday.
Illustrious career
The 58-year-old Woolmer had enjoyed more success as a coach than as a player.
He had a disappointing Test career even though, in only his second Test, he saved England as they followed on against Australia by holding out for 499 minutes against Dennis Lillee and Jeff Thompson to score 149.
He added two more hundreds, also against Australia, but he first interrupted his Test career by signing for World Series Cricket in 1977, and then ended it forever by joining the rebel South African tour of 1981-82.
As a coach, he pioneered the use of computers to understand a player's game. The creative and adventurous Woolmer also had a stint as ICC's high performance manager.
He became Pakistan coach in June 2004 and his contract was due to expire on June 30, 2007.
