KUALA LUMPUR : Malaysia has arrested more than a dozen members of an alleged people trafficking syndicate after intercepting a ship carrying 127 Sri Lankan migrants believed to be bound for Australia and New Zealand, authorities have said. Maritime authorities on Tuesday halted a modified tanker named "Etra" in Malaysian territorial waters off southern Johor state, national police chief Mohamad Fuzi Harun said.

Nearly 100 Sri Lankan men, 24 women and nine children were aboard the ship, which was making its way to international waters when it was stopped.

The police chief said in a statement Saturday that authorities arrested 16 people involved in an "international network" of people smugglers, including three Indonesians and four Malaysians aboard a fishing vessel used to transport the migrants from the Johor coast to the tanker.

Another four Malaysians were arrested in the nearby state capital of Johor Bahru, while a fifth was taken into custody in northern Penang state. Four Sri Lankan men were arrested aboard the tanker for suspected involvement in the trafficking network.

Mohamad Fuzi said the remaining 127 passengers aboard the vessel had been detained for violating immigration laws, according to news reports which did not say where they were being held or if they had been allowed to disembark.

He said the international syndicate, which covered Sri Lanka, Australia, New Zealand, Indonesia and Malaysia, had been operating since the middle of last year. It is relatively rare for people-smuggling boats seeking to take people to Australia to be stopped off Malaysia. Boats typically bypass Malaysia and head to neighbouring Indonesia, the traditional staging post on the route to Australia.  Over the years, many such vessels have been stopped or have sunk off Indonesia.
