Police in Jamaica investigating the murder of Pakistan's cricket coach Bob Woolmer say they could be searching for more than one attacker.
They said today Mr Woolmer may have known his killer or killers, and they are studying video footage from the Pegasus Hotel.
Members of the Pakistan team and staff have been interviewed, and they have asked police to allow them leave Jamaica as soon as possible.
They are expected to return to Pakistan over the weekend.
Mr Woolmer, who was 58, was strangled in his room hours after Pakistan lost to Ireland in the cricket World Cup.
The deputy police commissioner in Kingston, Mark Shields, earlier today said that it looked as if it might have been somebody somehow linked to him.
Mr Shields said that Mr Woolmer had let somebody into his hotel room and it may be that he knew who that person was.
He said that police were probing video recordings from the hotel's closed circuit television cameras but had not yet found anything suspicious.
He also dismissed rumours that arrests had been made.
Jamaican police yesterday questioned members of Pakistan's cricket squad over the death and took fingerprints.
Pakistan team spokesman Pervez Jamil Mir said the players were 'in a state of shock' over the news that Mr Woolmer had been killed.
Police confirmed overnight that post-mortem results showed the 58-year-old died from manual strangulation.
Mr Woolmer was found unconscious in his hotel room on Sunday morning last, just hours after Pakistan's shock defeat by Ireland in the Cricket World Cup.
He died in hospital a short time later.
A police spokesperson said they were following a number of lines of inquiry.
It has been confirmed that the former head of the London Metropolitan Police, Sir Paul Condon, is to assist in the investigation.
