Pakistan's cricket coach Bob Woolmer was incapacitated by drugs before he was strangled, a British Broadcasting Corp investigative programme said on Monday. Preliminary toxicology tests, due to be given to Jamaican police next week, indicated that Woolmer had been incapacitated by a drug, the BBC's Panorama programme said.
The programme did not identify the drug or the source of its information.
Woolmer, a 58-year-old former England Test batsman, was found unconscious in his room and later declared dead on March 18, the day after his squad was upset by Ireland and eliminated from the World Cup. Police said he was strangled.
Woolmer's body was returned to his family in South Africa on Sunday.
In an interview with the programme, investigating officer Mark Shields said it would be difficult to strangle a man as large as Woolmer.
"A lot of force would be needed to do that," Shields said. "Bob Woolmer was a large man and that's why one could argue that it was an extremely strong person, or maybe more than one person, but equally the lack of external injuries suggests that there might be some other factors and that's what we're looking into at the moment."
