For being linked with yet another terrorist cell.
Radical Muslim preacher linked to Bali arrested in Indonesia - Telegraph:
"Abu Bakar Bashir, 71, co-founder of Indonesia's deadliest terror group, al Qaeda-linked Jemaah Islamiyah, was accused of providing vital support for an extremist cell plotting a wave of assassinations and high-profile attacks.
He was seized in West Java, where a plot to kill President Susilo Bambang Yudhoyono was uncovered last week, and taken to Jakarta for questioning.
Mr Bashir was arrested twice before and spent 30 months in jail for conspiracy over his links to the 2002 Bali bombings in which 202 people - mostly Australian tourists - were killed.
But he was acquitted and released in 2006.
