The Netherlands has sent police to help search for missing American teenager Natalee Holloway and Aruban authorities hope a Dutch television program will generate new leads, officials said Wednesday.

The program, to air on April 11 in Aruba and the Netherlands, will re-enact Holloway's known final hours on the Dutch Caribbean island and offer a toll-free hot line for people to call with tips, the Aruba Public Prosecutor's Office said.

Holloway, of Mountain Brook, Ala., was last seen on May 30, the final night of her high school graduation trip to the island.

Investigators believe there are people on the island who have important information about the case but have not yet come forward, the prosecutor's office said in a statement.

The program, "Opsporing Verzocht," which translates as "Arrest Requested," has helped authorities solve 30 percent of cases it has featured over the past 22 years, the prosecutor's office said.

Dutch police spokesman Ed Kraszewski confirmed that a group of police officers went to Aruba from the Netherlands to help in the Holloway case, but wouldn't give details.

Dutch Marines, the FBI and hundreds of volunteers have previously searched for Holloway.

Holloway, who was 18 when she disappeared, was last seen leaving a bar with three young men, who were arrested in June and later released after a court ruled there was insufficient evidence to hold them.
