JAKARTA?Indonesian police said Wednesday they had seized three remote-controlled bomb detonators at the Internet cafe on Jakarta's outskirts where fugitive militant leader Dulmatin was killed.

National police chief Bambang Hendarso Danuri told reporters that the devices were ready to be used, but refused to say whether any explosives had been found in Tuesday's raid on the cafe in Pamulang city.

"We found detonators to be used to trigger bombs from a distance," he said.

Dulmatin's death came after security forces conducted a series of raids in Jakarta, West Java and in Aceh, where an extremist training camp was discovered.

"Dulmatin's role was to prepare military training, buy weapons and bullets and finance military training activities with funds of 500 million rupiah (54,500 dollars)," Danuri added.

The Al-Qaeda-trained bomb specialist with a $10-million bounty on his head was killed by police, President Susilo Bambang Yudhoyono said Wednesday, confirming earlier police reports.

Danuri also said that 28 terror suspects were arrested and three policemen killed in the anti-terror crackdown.

He said the raids were targeting Jemaah Islamiyah (JI), the Southeast Asian extremist group inspired by Al-Qaeda and blamed for multiple attacks across Indonesia, including the 2002 Bali bombings which killed 202 people.

Danuri said police had seized nine firearms and tens of thousand of bullets, including those for assault rifles such as M-16 and AK-47s during the raids.

"The series of raids are not over yet... we will continue our efforts to fight all the terrorist activities in Indonesia. We will never stop," he said.
