Jamaican police have confirmed they are studying 'critical' CCTV footage of the hotel where Pakistan coach Bob Woolmer was murdered.
Woolmer was found dead last Sunday after being strangled in the Pegasus Hotel in Kingston, the day after Pakistan were surprisingly knocked out of the World Cup by Ireland.
Police are pursuing a number of lines of inquiry with speculation rife Woolmer, 58, may have been preparing to speak out on match-fixing.
Woolmer's room was on the 12th floor of the hotel and police feel he may have known his killer - or killers - as there was no sign of forced entry.
Deputy police commissioner Mark Shields said: 'We are still looking at CCTV. It is pretty comprehensive. Unfortunately it does not show the doors but shows the corridors at either end and will give us an indication who was on that floor. It is critically important because it may give us an image or images of the killer of Bob Woolmer.'
Shields also played down reports Woolmer had been involved in an argument with players on the team bus after the Ireland defeat at Sabina Park.
The Pakistan team have now left Jamaica and are in London en route to Lahore. The entire party were questioned by police during the week with captain Inzamam-ul-Haq and coach Mushtaq Ahmed required for further questioning before their departure on Saturday.
Shields pointed out that this was merely to complete formalities and clear up ambiguities.
