The police counter-terror squad, Detachment 88, found a bomb almost identical to ones believed to have been used in the second Bali bombings that killed 23 people in October last year, during the raid on Noordin Mohammed’s hideout in central Java on Saturday.

The bomb was found on Sunday night inside a house in Jatiwungu village in Temanggung regency, central Java, after information was gained from the two militants arrested after a weekend raid on their hideout, National Police spokesman Brigadier General Anton Bachrul Alam said.

The bomb was active. All the materials used for the bomb were exactly the same as those used in the second Bali bombing. And so is the method of how the bomb was prepared.

Anton said the bomb was packed in a backback similar to the ones carried by bombers who struck in Kuta last year.

A police forensics report on the last Bali attacks said the chemicals used in the bombings were TNT (trinitroluene), PETN (pentaerythritol tetranitrate), chlorate and sulfur. At the bomb site in Kuta, police also found hundreds of iron pellets.

Anton said the two terror suspects, Sholahuddin and Mustaghfirin, told police about the bomb during interrogation sessions. The pair were arrested in Saturday’s predawn raid on a house in Wonosobo, Central Java. Two other militants were killed in the raid.

Police believe the two surviving men are connected to the al-Qaeda-linked terror group Jamaah Islamiyah.

It is possible that the investigations by the counterterrorist squad will lead to further developments in this case.

Anton said.

Police were maintaining checkpoints at central Java border areas to capture one of Asia’s most wanted-terror suspects, Noordin M. Top, he said.

We hope that the investigators will be tipped off again of by information from citizens, like what happened in Wonosobo.

Anton said the Saturday raid in Wonosobo occurred after close cooperation between local residents and the authorities.

Police confiscated two firearms, several laptop computers, a desktop PC, nine cellular phone cards, several bags, a detonator and stacks of documents during the raid. On one of the computers a video was found which gave detailed instructions on how to make bombs.

Some of the documents contain copies of statements by the previous suicide bombers explaining the reasons why they did what they did.

He said the group probably was planning to use the statements as propaganda for recruitment purposes.

Last November, police discovered video recordings containing statements believed to be from three suicide bombers who carried out the 2005 Bali attacks, which killed 23 people.

In the video, a person who identified himself as Salik Firdaus told his family he loved them and said when they saw this tape, he would already be in heaven.
