An Islamic teacher suspected of links to a key leader of a Southeast Asian terrorist organisation has been arrested in a central Indonesia, police said on Saturday.
Sahal Alamri was detained on Thursday in Poso in Central Sulawesi province before being flown to Jakarta for questioning, police chief Brigadier General Oegroseno said, according to the state news agency.
Alamri was suspected of links to Noordin Mohammad Top, a Malaysian wanted by Indonesian police for allegedly masterminding a series of deadly attacks in Indonesia in recent years, the report said.
Poso has been the scene of Muslim-Christian violence which killed more than 1,000 people between 1999 and 2001.
A government-brokered truce went into force in December 2001 but intermittent bombings, shootings and other attacks have continued in Poso and surrounding areas.
Noordin was a key leader of the Al Qaeda-linked regional terrorist network Jemaah Islamiyah (JI), but experts have said they believe he later split to create an even more hardline group.
JI has been blamed for most deadly attacks in Indonesia in recent years, including the bombing of Bali nightspots in October 2002, which killed 202 people -- mostly western holidaymakers.
