“There was an arrest of a suspect of that bombing,” East Java Police Chief Inspector General Firman Gani said.

The suspect, identified as Dahlan, was arrested from the East Java town of Ngawi.

Blame

The attack on the Marriott hotel is blamed on Jemaah Islamiyah, a regional group linked to Usama bin Ladin’s al-Qaida.

Jemaah Islamiyah is also accused of the bombings in Bali in October 2002 which killed 202 people.

Four men are already on trial in Jakarta for their alleged roles in the Marriott bombing and trials of several others are due to follow.

An Indonesian court last week sentenced to 10 years in jail a man found guilty of having stored raw materials to build the bomb used in the hotel blast.

Two key suspects, Nur al-Din Muhammad Top and Azhari Husayn are still being hunted for the Marriott attack.
