JAKARTA - ANOTHER Singaporean is among the four men Indonesia's anti-terror squad nabbed in southern Sumatra over the weekend.

The man, identified by police as Syamsul, 50, was detained in a village in Bandar Lampung after the arrests of Singaporean fugitive Husaini Ismail and another Indonesian, Saefuddin Zuchry, in Central Java.

Six suspects in all have been rounded up by the anti-terror squad Densus 88 in a crackdown on the Jemaah Islamiah (JI) terror network; two in Central Java and four in Sumatra's Lampung province. Syamsul was never mentioned in previous reports on Singaporean terrorists on the run.

The focus has been on a five-men terror cell that plotted to hijack a plane and crash it into Changi Airport in 2001.

The cell was headed by Mas Selamat Kastari, who fled Singapore that year when the Internal Security Department (ISD) rounded up JI members.

Lampung police criminal investigation chief Darmawan Sutawijaya said yesterday that Syamsul was arrested after three months of intense surveillance by his men and Densus 88.

The chief told Antara news agency that initial investigations showed that the man was a member of the Singaporean terror cell led by Mas Selamat.

The cell's second-in-command, Mohammad Hassan Saynudin, 36, is serving an 18-year jail term after being convicted of terrorism by a Jakarta court in April.

Senior Commissioner Darmawan did not say whether Syamsul was related to Husaini but reports in the Jakarta Globe and the Viva News online newspaper yesterday said that one of the men detained in Lampung was the younger brother of Husaini.

The man was identified as Somad or Samad, but it could not be confirmed yesterday whether those are the aliases of Syamsul. Many JI members are known to go by various names.
