The inquest into the death of Pakistan cricket coach Bob Woolmer has been postponed because of "significant developments" in the case.
It is thought Mr Woolmer was strangled
Woolmer was found dead in his Kingston hotel on 18 March, the day after his side lost to Ireland in the World Cup.
The inquest was set for 23 April but has now been delayed after recent, undisclosed findings.
"The coroner has been advised there are recent and significant developments," the Jamaican justice ministry said.
"These new developments are critical to the progress and the eventual result of the investigation."
The results of the new findings will determine whether the inquest will be held at a later date, the statement went on to say.
It is believed the ex-England batsman was strangled.
Police probing Woolmer's murder had sent CCTV images to Scotland Yard for further consideration.
A team of four officers from Scotland Yard are in Jamaica to help with the inquiry, following a formal request from the Jamaican authorities.
Pakistan also sent as an observer senior police investigator Mir Zubair Mahmood, who led the investigation into the murder of US reporter Daniel Pearl in Karachi.
He and another security official had come at the request of the Jamaican government, an official said.
Two forensic experts from Interpol, the France-based international police agency, have also been helping the investigation.
Jamaica's deputy police commissioner Mark Shields has said the foreign investigators will help with DNA analysis and also examine theories that Woolmer may have been poisoned before being strangled.
