Pakistan coach Bob Woolmer has died after being found unconscious in his hotel room in the West Indies.
Pakistan's involvement in the competition ended with a shock three-wicket defeat at the hands of Ireland yesterday.
The 58-year-old former England Test batsman was discovered in his room at the Pegasus Hotel in Sabina Park this morning, and was immediately taken to the emergency department of a nearby hospital - but he did not recover.
The team's media manager Pervez Mir revealed that Woolmer suffered from a medical condition - but said it was too early to say whether it played a part in his death.
A team spokesman said: “We saw him last night but having not seen him early today two of our officers went to his room and with the help of hotel staff entered. He was found unconscious there.
“It is too early to say whether he has suffered a heart attack. We are awaiting medical reports.”
A statement is expected to be released by the Pakistan Cricket Board, and Woolmer's South Africa-based wife has been notified.
Woolmer, who has also coached South Africa and Warwickshire, was contracted to the Pakistan Cricket Board until the end of the tournament.
Woolmer was last in the news when Pakistan toured England last summer.
His side became the first in Test history to forfeit a match after they initially refused to take the field following an incident involving Australian umpire Darrell Hair.
Hair awarded England five penalty runs after deeming Pakistan guilty of ball tampering during the match at the Oval.
Inzamam-ul-Haq's side continued the game at first but later refused to carry on.
Pakistan did offer to take the field eventually but Hair, along with fellow umpire Billy Doctrove, had decided to award the game to England.
Pakistani cricket fans today reacted angrily to Pakistan crashing out of the World Cup.
Effigies of the players have been burnt in the streets following the shock defeat to Ireland.
