Lockerbie bombing: British detectives to fly to Libya for the first time Mr Cameron said that so far Metropolitan Police officers had been to Tripoli three times to investigate the murder of WPc Fletcher. Asked if he wanted to see the people behind the murder of WPc Fletcher or the bombing of a Pan Am jet over Lockerbie in Scotland, which killed 270 people in 1988, brought to justice, he said: "In all these cases I want to achieve justice and the full uncovering of all the facts. Progress has been made but we have to understand the growing capacity of the Libyan Government to deal with these requests and we have to work with them as their capacity grows so we can work with and solve these issues. Do I want the truth to be uncovered, for justice to be done, yes of course. Mr Zeidan added that the Libyan Government too "wants to know what happened." He disclosed that on the day WPc Fletcher was murdered he was in London protesting outside the embassy, near the police officer. He said: "I was one of the injured in 1984." He added that "after justice is achieved, facts are achieved, the truth is disclosed, everything can be discussed." Britain's top prosecutor has said he wants the chief suspect in the WPc Yvonne Fletcher murder case to be tried in the Old Bailey. Last year, Keir Starmer, the Director of Public Prosecutions, said that in his view "the case should be tried here in London." However, Mr Starmer, who heads up the Crown Prosecution Service, said that more evidence was needed before any charges could be made in the case. Matouk Mohammed Matouk, who is thought to be the only surviving Libyan who can be charged over the murder, could be extradited to Britain to face trial. Matouk was named as a suspect who could be charged with conspiracy to cause WPc Fletcher's death in a secret CPS review of the police investigation, which was disclosed by The Daily Telegraph in 2007. Ministers have resisted pressure to request that Matouk is extradited, saying that Britain wants to give the new Government in Libya time to establish itself first. The situation is further complicated by a five year old agreement between Britain and Libya which says Tripoli should have the final say on where anyone should be tried over the killing. Britain also has no extradition treaty with the north African country. In an interview with The Daily Telegraph, Mr Starmer said the Metropolitan Police had more work to do before anyone could be charged over the case. He said: "We gave advice in 2007. It was clear from that advice that some further work was going to be needed if criminal proceedings could be brought. We thought then that the work could be done. The environment has now changed radically. We support the police in the further work that want and intend to carry out.
