The security forces in the Philippines have discovered a headless body suspected of belonging to Sarawakian engineer, Bernard Then Ted Fen, who was abducted by four armed men in Sandakan, Sabah, last May.

Deputy Foreign Minister Datuk Seri Reezal Merican Naina Merican said the body had been referred to Then's family last night (Monday) for identification purposes and further action.

However, Reezal Merican did not reveal when the Filipino security forces found the body. He said this when winding up the Supply Bill 2016 debate for his ministry at the Dewan Negara here Tuesday, while expressing his condolences to the family members of the victim.

It had been reported that Then, 39, was beheaded in a remote location considered to be a stronghold of the Abu Sayyaf militants in the southern Philippines.

Then was abducted by a group of armed men at a seafood restaurant in Sandakan, Sabah on May 14, along with the restaurant manager, Thein Nyuk Fun, 50.

Thien however, was released on Nov 8. Prime Minister Datuk Seri Najib Tun Razak on Nov 18 mentioned on his Facebook and Twitter pages that Malaysia strongly condemned the killing of Then.

Reezal Merican explained that the Government of Malaysia through its enforcement agencies always enforced the law and regulations to defend the sovereignty, security and safety of its citizens as well as foreign tourists.

He pointed out that the acts of aggression and violence was not only criticised by Malaysia, but also the Philippines government.

"The government will not take lightly the issue of abductions, and will take appropriate action. "The government is also looking at approaches in the bilateral and multilateral-level to find solutions to issues that involve incursions and kidnappings," he added.
