Aruba's prime minister has urged investigators to give the FBI all documents related to Natalee Holloway's disappearance.
Prime Minister Nelson Oduber asked in a letter to Attorney General Karin Janssen that the bureau be allowed complete access to transcripts, audio tapes and all other materials.
FBI agents have been advising Aruban authorities in the six-week-old investigation. But Aruba's government spokesman, Ruben Trapenberg, says the agents haven't had access to case records.
FBI spokeswoman Judy Orihuela says the agency has pressed for access to the documents.
Trapenberg says the attorney general hasn't yet responded to the government's request. The attorney general could not immediately be reached for comment Friday.
18-year-old Holloway vanished May 30 while on a graduation trip to the island.
17-year-old Joran van der Sloot remains in custody in connection with the case.
