Police in Kingston has said that it is "unlikely" that Pakistan coach Bob Woolmer's killers were Jamaicans.

The police have consistently said that they are confident the killer or killers was known to Woolmer because of the fact there was no sign of unforced entry and nothing was stolen.

"The fact that it is manual strangulation and asphyxiation does not lead to the profile of somebody locally, where you tend to find firearms or knives as the favoured weapons," Deputy Commissioner of Jamaican Police and former Scotland Yard officer Mark Shields told Britain's Sky News.

"You can never dismiss anything, but at the moment it seems highly unlikely a Jamaican has walked off the street, gone up to the 12th floor in a secure lift, gone along to his room, got into his room without any sign of forced entry, murdered him and then not stolen anything at all," he said.

Shields, however, refused to dismiss the idea a hitman may have been responsible.

"I rule absolutely nothing out at all. It's a possibility," Shields said.

Shields also said that he is not prepared to put a timeline on solving the case and although he is optimistic it could take two days or two years.

Shields also confirmed the International Cricket Council's Anti-Corruption Unit's General Manager Jeff Rees is investigating any possible links between the murder and match-fixing.

"The match-fixing aspect of this is being carefully handled. Jeff Rees from the ICC is here at the moment. He is going to assist us. I promised him a couple of officers to work along with him."
