ANGELES CITY -- Police are now hunting an American woman after the regional trial court here issued two warrants of arrest for libel against her.

Judge Maria Angelica Paras-Quiambao issued the arrest warrants against Maribel Langley-Van Keulen, 41, who is claiming to be a member of the National Press Club (NPC).

This developed after the Supreme Court junked her petition for writ of amparo.

Langley-Van Keulen earlier filed before the high court a writ of amparo against Philippine National Police (PNP) Director General Jesus Versoza, National Bureau of Investigation (NBI)-Central Luzon director Rustico Vilgilia, and 10 other police officials in this city, including Chief Inspector Luisito Tan, one of those who filed libel charges against her.

Van Keulen is being suspected as author of the website centralluzoncorruption.com, which labels President Gloria Macapagal-Arroyo as "thief and murderous president," among other scandalous terms, and the Philippines as the "murder capitol (sic) of the world."

The website claimed that last August, US President Barrack Obama himself had asked President Arroyo, whom it referred to as "the buck-toothed dwarf," to ensure Van Keulen's safety in the Philippines.

In her writ for amparo, Van Keulen claimed that policemen in this city had been harassing and even threatening her life after her efforts to make investigative reports of human trafficking and prostitution here allegedly involving collusion between law enforcers and bar owners.

Van Keulen's petition was junked by the High Court en banc last October, noting that she failed to submit proof that a copy of her petition was served to the respondents.

An official certification from Branch 1 of the Municipal Trial Court (MTC), signed by clerk of court Abnel Romeo Sicat, said that Van Keulen is also facing other cases for alarm and scandal, simple oral defamation, and serious resistance and disobedience to an agent of a person in authority.

Van Keulen reportedly claimed to be a Filipino-American but Bureau of Immigration (BI) Clark chief Eranio Manalo said his office's record indicated that the former is an American national.

Immigration records also indicated that her latest recorded arrival was on January 1, 2006. "There is no record of her extending her visa," Manalo said.

In an affidavit, George Cayanong of the Lupon ng Tagapamayapa (peace council) of Barangay Balibago here said Van Keulen had identified herself as a reporter with links to Malacañang.

He issued the statement in relation to a complaint filed in August this year by one Raquel Manez, who accused Van Keulen of non-payment of apartment rentals.

NPC president Louie Logarta confirmed Van Keulen is an affiliate member of the NPC although he noted that she did not identify her media outfit.

"She claimed to be doing investigative reporting for a correspondent of a national paper," Logarta said.

One of the libel cases, filed by Tan and civilians Jonathan Ponce and Elpidio Lim, was based on the website centralluzoncorruption.com which, Van Keulen earlier denied being involved with.

Government counsel Mark Oliver Sison, in a certification, stated that Van Keulen exposed the respondents "to public hatred, contempt and ridicule" by "unlawfully and feloniously" publishing in the website the respondents' photo whose caption identified them as undercover cops engaged in extortion at the tourism district of this city.

Tan said he was sure that the website has been under Van Keulen's control, as he cited the photo which he witnessed her taking with the use of her cell phone. He also noted that the website's updates conform to Van Keulen's involvements in this city.

The website published articles with vulgar words accusing top political, police, and even media personalities of anomalies. It also cites the Philippines as the "murder capitol (sic) of the world."

The website said: "Murder has become the primary tool whereby the Philippine Islands' state seeks to control the organs of liberty... They already control the judiciary. We can prove that some news-people have valuable intelligence that once revealed would help their own people, but they are afraid to even allow us to print it for them." (Reynaldo G. Navales)
