Pakistan cricket coach Bob Woolmer was poisoned before being strangled in Jamaica during the World Cup, a BBC documentary will reveal tonight.
Woolmer was found dead on March 18th , a day after Pakistan were eliminated from the World Cup following a shock defeat by Ireland.
The BBC's Panorama, in an investigation due to be screened tonight, says that preliminary toxicology tests showed that Woolmer was subdued by a drug that left him helpless.
He was then both strangled and smothered, the BBC World Service said in a report ahead of tonight's broadcast. The drug used had not yet been identified, it said.
Newspaper reports said the programme would also screen the last recorded image of Woolmer, taken after Pakistan's shock defeat.
A blurred recording from a CCTV camera at the Pegasus Hotel shows the coach heading back to his room on the 12th floor, where his body was found the following morning.
Police in Jamaica have not yet made any arrests over Woolmer's death, which cast a shadow over the cricket World Cup that ended on Saturday and was won by Australia.
The BBC said in its radio report that the findings suggested his killing was premeditated rather than being "a spur-of-the-moment act of violence".
