An Indonesian newspaper is reporting that Indonesian police have arrested a man believed to have played a key role in September's car bombing outside the Australian Embassy in Jakarta.

Indonesia's leading newspaper, Kompas, quotes police sources as saying Iwan Darmawan, also known as Rois, was arrested two weeks ago on Java island.

The newspaper quoted the police sources as saying Mr. Darmawan is accused of having a key planning role in the September 9 embassy attack, which killed 10 people.  He is also accused of being involved in the 2002 Bali bombings, as well as last year's car bombing attack on a Jakarta luxury hotel.

Police have said two Malaysian militants, who remain at large, are the masterminds of the embassy attack.
