Findings from a post mortem into the death of Pakistan coach Bob Woolmer were "inconclusive" and further tests are being carried out, the Pakistan Cricket Board said on Tuesday.

"The pathologist's findings were inconclusive and he is awaiting results from toxicology and histology (the examination of body tissue) from the government's forensic laboratory," PCB spokesman Pervez Mir told a news conference.

Woolmer, 58, was found unconscious in his Kingston hotel room on Sunday after his team had been eliminated from the World Cup by debutants Ireland less than 24 hours earlier. He died later in hospital.

The death has rocked the tournament.

Former England Test batsman Woolmer, a diabetic, was regarded as one of the premier coaches in the world but the position with cricket-crazy Pakistan was one of the most pressurised in the sport.

Mark Shields, deputy commissioner of the Jamaican police constabulary (crime division), said that the body could not be released until the pathologist had completed his examination.

"We can't rule anything out. It's our position to investigate. We have to wait for the pathologist to provide a report which will go to the coroner. From that, we will know what action we will take next," he told the news conference.

'UTMOST URGENCY'

"If there are no results we will not be able to release the body unless the coroner gives his authority.

"In a case like this I would think the pathologist would want to be absolutely sure and so I see nothing unusual in that.

"He wants to make sure that whatever his findings are they are accurate. Therefore conducting further tests is quite legitimate and sensible in these circumstances.

"I know that the scientists are treating it with the utmost urgency in order that we can hopefully repatriate the body to his family as soon as possible," added Shields.

Asked when the scientists' conclusions would be available, Shields replied: "I just know they are working as quickly as possible to provide the information that we need. I hope it's today but it could be tomorrow."

The police had earlier said Woolmer died in hospital at 12:14 p.m. local time on Sunday.

Pakistan face a final match in Group D against Zimbabwe at Sabina Park, Kingston, Jamaica on Wednesday before flying home on Saturday. They have lost both their matches so far and the defeat by Ireland was the biggest shock so far in the event.

Mir said the intention was that the body would be returned to Woolmer's family in Cape Town via London.

The seven-week World Cup culminates in a April 28 final in Barbados.
