[JURIST] Indonesian police said Tuesday that they have arrested a man identified simply as "Hasan" in connection with the October 1 Bali bombings [BBC report], the first arrest in the case. Hasan shared a rented house in Bali with the three suicide bombers who blew themselves up as part of a coordinated attack. Under Indonesia's current anti-terror law [JURIST report], Hasan can be held for up to seven days before being charged. The suicide bombers are believed to be involved with al Qaeda-linked militant group Jemaah Islamiyah [BBC profile]. Australian officials have called on the Indonesian government to ban the group [JURIST report], but Indonesia says that it cannot do so [JURIST report] because the government has never formally acknowledged the group's existence. AP has more.
