KEY POINTS:
Jamaican police have reportedly found traces of poison in the hotel room where dying Pakistan cricket coach Bob Woolmer was found.
Investigators say his death is being treated as "suspicious".
Woolmer, 58, died on Sunday after collapsing at the team hotel, hours after Pakistan's shock loss to Ireland and early exit from the World Cup competition.
Deputy Police Commissioner Mark Shields said there would be a full investigation into the death.
"Having met with the pathologists and other medical personnel, there is sufficient information to continue a full investigation into the circumstances of Mr Woolmer's death, which is now being treated as suspicious," he said at a news conference.
Police earlier said that an autopsy on the former England batsman was inconclusive.
Pakistan's GEO television network reported that Woolmer was poisoned, without specifying if it was thought to be suicide or murder. Woolmer was discovered in a pool of vomit, GEO said, with blood found on the bathroom floor.
Former Pakistan pacer Sarfaraz Nawaz earlier claimed that Woolmer was murdered by a betting syndicate. He speculated that Woolmer was about to reveal all in a book.
Nawaz said a former Pakistan Cricket Board official, who requested anonymity, said Woolmer's book, Discovering Cricket, could have exposed the cricketer-bookie nexus in Pakistan, India, and South Africa.
The official claimed Woolmer met Delhi police during Pakistan's 2005 tour of India to gather material for the book. Nawaz said the book was more than 50 per cent complete.
Nawaz also claimed that Pakistan Cricket Board insiders told him that at least five leading bookies from Pakistan had arrived in the West Indies in the first week of this month.
The Pakistan team will not be allowed to leave Jamaica until the investigation into Woolmer's death is completed. They may be shifted to a hotel in Montego Bay after playing their last Group D match against Zimbabwe today and stay there till the investigation is finished.
In an emailed statement, the ICC, the governing body that runs the World Cup, said: "The Pakistan management indicated they were comfortable with the arrangements surrounding the team and that the match would take place."
Pakistan Cricket Board spokesman Ahsan Malik said in a telephone interview from Lahore: "There is no authentic report thathe [Woolmer] was poisoned or how hedied.
"It is a sensitive issue so we are waiting for the outcome of the medical reports and police investigation."
