UK and Libya to set up joint police team to investigate Yvonne Fletcher murder Mr Shamis also attacked the "mind-boggling" delay in the investigation, which has so far lasted 28 years without any arrest. Mr Hague said that the prime minister, Abdurrahim el-Keib, had "apologised" for the comments. He said: "The Metropolitan Police are very pleased with their co-operation from the provisional government, who have agreed to appoint an investigative team. The next meeting with the Met will take place this week, so I can see that this investigation is being pursued with energy here in Libya. Prime Minister el-Keib was surprised to hear any reports to the contrary, and apologised for any comments from his own department which suggested otherwise.
