Police in Jamaica investigating the murder of Pakistan cricket coach Bob Woolmer have appealed for more witnesses to come forward.
Bob Woolmer was a former England Test cricketer
Deputy police commissioner Mark Shields urged people who had visited Kingston's Pegasus hotel in the 72 hours before Woolmer's death there to get in touch.
And he urged fans or tourists who had already left Jamaica to contact police.
Woolmer was found strangled in his hotel room after Pakistan's surprise World Cup loss to Ireland on 17 March.
"What I need to do is to identify everybody in the hotel from Friday through to Sunday when Bob's body was found, in an effort to establish everybody's movements during that period of time," Mr Shields said.
Mr Shields has hit out at media speculation over the case
"Not just as suspects but as potential witnesses - people who may have heard something, seen something within the hotel that raised their suspicions, that so far they haven't come forward with."
Mr Shields urged potential witnesses to call a special telephone hotline.
And he told Reuters news agency that the case could take months. "There are numerous avenues of inquiry that are open to us," he said.
'Nobody ruled out'
Police are continuing to review CCTV footage of the hotel in the hope of identifying a suspect. They are also examining the hard drive of Woolmer's computer for anything which might establish a motive for the murder.
Detectives believe Woolmer probably knew his killer - or killers - as there were no signs of forced entry into his room and none of his belongings had been stolen.
There has been speculation that the murder is connected to match-fixing allegations which have haunted cricket for the past decade.
Several Pakistan players were fined and banned from the game after being found guilty of match-fixing by a judicial commission in the late 1990s.
Speaking to the BBC, Mr Shields rejected earlier comments by Pakistani team spokesman Pervez Mir suggesting team members were in the clear.
"That's a pretty inaccurate statement, because nobody at this stage can be ruled out of the inquiry," he said.
