The police have detained another suspected member of an al-Qaeda-linked regional terror group blamed for the Bali bombing last October.

Mohamad Amin Musa, 29, was picked up o­n Sunday in southern Johor state and was being held under the country's Internal Security Act as a Jemaah Islamiyah (JI) suspect, a police spokesman told AFP o­n condition of anonymity.

"Police are investigating his role in JI, and what he knows as well as his links to the top JI leaders who are still o­n the run," he said, adding that eight Malaysian members of JI remained o­n the police's most wanted list.
