MADRID, Spain (AP) _ Spanish police have arrested an Algerian suspected of being a member of a terrorist organization, a spokesman said Wednesday.

Tahar Izerouel was arrested Tuesday night in Bilbao on an order from leading terror investigator Judge Baltasar Garzon, National Police spokesman Antonio Nevado said.

It was not immediately possible to confirm if Izerouel was one of eight people indicted by Garzon on terrorism charges for providing logistical help and false documents for suspects in the Sept. 11 attacks in the United States.

In the indictment, released Monday, Garzon had ordered the arrest of a suspect named Tahar Ezirouali.

Garzon said the eight had provided logistics and counterfeit documents for suspects including Ramzi Binalshibh, an alleged would-be Sept. 11 hijacker who has been in U.S. custody since his 2002 capture in Pakistan. He is believed to have been the main contact between a group of Sept. 11 attackers in Hamburg, Germany, and Osama bin Laden's al-Qaida network.

The other seven charged were identified as Reda Zerroug, Redouane Zenimi, Samir Mahdjoub, Mohamed Ayat, Hedi Ben Youssef Boudhiba, Khaled Madani, and Spaniard Francisco Garcia Gomez.

All were charged with membership of a terrorist organization except Ayat and Garcia Gomez, who were charged with collaboration.

Garzon said they developed ``a network of forgery of documents to provide false identities or fake documents to other members of the network to help them move about, flee or hide or (to help) with their terrorist activities or links with organizations such as Ansar al-Islam, under the orders of Abu Musab al Zarqawi.'' The latter is a Jordanian-born militant blamed for spearheading terrorist actions in Iraq.
