The alleged deputy commander of a militant group linked to al-Qaeda and blamed for last year's Bali nightclub bombings has been arrested in Indonesia.
Idris was detained in Medan city on Sumatra island, Bali's police chief Major General Mangku Pastika said.
"He has confessed to his entire role in the bombing," Maj Pastika said. "This is a very important arrest." He said Idris had been caught after being part of a gang that robbed a Medan bank. The money was to be used to "fund a future operation," he said.
He gave no other details, but prosecutors have accused Idris of being the deputy of Mr Imam Samudra, the alleged mastermind of the Bali bombings.
Mr Samudra is on trial on the resort island for the attack, which killed 202 people, including 26 British holidaymakers.
Idris has been on the run since the October 12th bombings. He tops the police's most wanted list of suspects in the attack.
Prosecutors say Idris (35), is a member of Jemaah Islamiyah, a regional al-Qaeda-linked Islamic group accused of carrying out the Bali attack.
Jemaah Islamiyah allegedly aims to set up a regional fundamentalist Islamic state by using terror attacks to topple Southeast Asian governments.
