Police in Indonesia say they have arrested the alleged military leader of Jemaah Islamiah, the extremist group blamed for the 2002 Bali bombings.
Abu Dujana is Indonesia's most wanted Islamic militant
Abu Dujana, Indonesia's most wanted Islamic militant, was arrested on Saturday on the island of Java.
Seven other suspected militants were arrested with him.
Analysts say the arrest is a major victory for Indonesian security forces in their fight against Islamic militants.
As well as the Bali bombings of 2002, Jemaah Islamiah (JI) is accused of carrying out a string of other crimes, including an attack on the Australian embassy in Jakarta in 2004 as well as a car bombing at the city's Marriot hotel a year earlier.
Abu Dujana was wanted in connection with both of those attacks, police say.
The arrests were made at a house in central Java on Saturday, although police did not confirm that 38-year-old Abu Dujana was among those detained until early on Wednesday.
They say he operated under so many different aliases that it took several days to determine his identity, which was finally confirmed by fingerprinting and DNA tests.

Deputy police chief Makbul Padmanegara recently told reporters that Abu Dujana had replaced Noordin Mohamed Top, a Malaysian national considered a mastermind behind a series of bomb attacks in the country, as Indonesia's most wanted fugitive.
Now he is in custody, he will face a long list of questions about different attacks in Bali, Jakarta and the island of Sulawesi.
Police also want to question him about a series of attacks they say were being planned on an undisclosed location.
Earlier this year security forces found a large cache of bombs and bomb-making materials - enough, they say, to make an explosion four times as powerful as that used in any previous attack.
Analysts say Abu Dujana has key information about logistics and operations within JI, and his arrest will be a serious blow to the organisation.
"With this arrest we have successfully stopped acts of terrorism in the future," said police spokesman Sisno Adiwinoto. "He was a key figure in the terrorist network in Indonesia."
Leading Jemaah Islamiah analyst Sidney Jones also agreed that the arrest was "a major triumph for police".
"If he is willing to talk he will be able to tell the police about the structure, the strength, the finances and the international connection and the goal and objectives of JI," she told reporters.
Exact information about Abu Dujana is difficult to obtain, but police believe he had military training in Afghanistan in 1989, where he later fought with the mujahideen.
Like many senior members of JI, he is thought to have fled to Malaysia in the 1990s to avoid a crackdown by the former dictator Suharto.
Analysts say he probably became the military head of JI a few years ago.
