The tests, taken after Bob Woolmer was found strangled in his hotel room in Jamaica during cricket's World Cup tournament in March, were sent to Britain's Forensic Science Service to be independently verified, Jamaican deputy police commissioner Mark Shields said Monday.

The government-owned lab, which is the leading supplier of forensic services to police forces in England and Wales, confirmed it is examining the tests, but said it had nothing to report.

"We wouldn't comment on ongoing cases," lab spokeswoman Laura Mackin said. "We can confirm that we've got (the tests), but other than that, until there's some kind of conclusion, we wouldn't talk about the work that we're doing with the police."

The British Broadcasting Corp. reported earlier that a toxicology test on Woolmer's body showed the presence of a drug that would have incapacitated him.

The BBC's "Panorama" program did not identify the drug or the source of its information, but said results of toxicology tests were due to be given to Jamaican police within the next week.

Shields, a former Scotland Yard detective, has said in the past that foreign investigators would examine theories that Woolmer may have been drugged. He said that would have made it easier to strangle a man as large as Woolmer, a former member of England's cricket team.
