AMSTERDAM, 08/11/08 - Crime reporter Peter R. De Vries has again caught Joran van der Sloot, in many eyes the murderer of American teenager Natalee Holloway, in an undercover operation trap. De Vries now claims to have collected evidence that the young Dutchman is involved in women-trafficking in Thailand.

This Sunday (9 November), De Vries will show in his TV programme, he claims, that Van der Sloot offers women for sale in the Thai capital Bangkok for the Dutch prostitution market. On hidden camera he explains how he supplies girls for 10,000 euros each, who work for 300 dollars a month in Dutch brothels.

Van der Sloot, the son of a judge in Aruba, said in February to an infiltrator working for De Vries that he dumped the body of Natalee Holloway, a teenager from the American state of Alabama, in the sea. He said she died suddenly while they were engaged in sexual activities on a beach. To the surprise of many, including De Vries, the authorities in the Netherlands and the Netherlands Antilles did not consider this confession serious enough for Van der Sloot to be arrested. Since then, he has been in the Far East.

Now trouble is looming again for Van der Sloot. Daily newspaper De Telegraaf, for which De Vries is a columnist, disclosed Friday that the film that will be broadcast on Sunday shows Van der Sloot doing business in a hotel room, in the presence of two Thai prostitutes, with what he thinks is a Dutch sex industry entrepreneur who was in reality working for De Vries. The reporter, with a star reputation, said in the newspaper that the film provides evidence of preparations for human trafficking.
