Laju hijacking

Singapore Infopedia


On 31 January 1974,1 four men armed with submachine guns and explosives2 attacked the Shell Oil Refinery on Pulau Bukom Besar,3 an island south of mainland Singapore. After they failed to blow up the oil tanks, the group – dubbed the “Bukom bombers” by the newspapers – hijacked the ferryboat Laju at the Bukom jetty and held five crew members hostage.4 After several days of negotiation that involved the governments of Singapore and Japan, the hijackers agreed to release the hostages in exchange for a party of guarantors to ensure their safe passage out of Singapore. The incident ended on 8 February 1974, when the hijackers left for Kuwait.

The four hijackers began their operation by hiring a boatman on the pretext of wanting to go fishing. When the boat reached the Bukom area, they attacked the boatman and took over the craft. However, their boat ran aground on a coral reef, and they tricked a passing boatman to tow them to the island.5

Once on Bukom, they tried to hijack a vehicle to penetrate deeper into the refinery but failed.6 The explosives they planted at three oil tanks caused minimal damage. One of the tanks burst into flames, and firemen managed to put the fire out quickly. About S$15,000 worth of crude fuel oil was lost.7

The foursome failed to detonate their remaining explosives.8 To escape, they boarded the Laju, a ferry operating between Bukom and mainland Singapore. They took all five crew members on board hostage and ordered them to sail into international waters. Two of them, Low Nam Seng and Encik Amat bin Awang Cik, were pushed overboard.9 Marine police on patrol boats soon spotted and pursued the Laju. After the Laju came to a stop at the Eastern Anchorage, marine police boats, customs launches and navy gunboats surrounded it, and negotiations began.10

The four hijackers identified themselves as Hiroshi Kimura and Akira Sato from the Japanese Red Army, and Saleh Salim Ali and Husain Mohammad Saad from the Popular Front for the Liberation of Palestine.11 They said that their Bukom operation was to retaliate against imperialism and aimed at disrupting the oil supply from Singapore to South Vietnam, an act of solidarity with the revolutionary forces in Vietnam.12

After days of intense negotiations, during which two hostages escaped, the hijackers agreed to release the remaining hostages in exchange for a group of guarantors to accompany them on their flight from Singapore to Kuwait and to ensure their safety until Kuwait.13 This came after another group of terrorists seized the Japanese embassy in Kuwait on 6 February and took several hostages, demanding that the Japanese government send a plane to Singapore to take the Bukom bombers to Kuwait.

On 7 February, the four were taken to Paya Lebar Airport, where they surrendered their arms, released the hostages, and boarded a specially arranged Japan Airlines (JAL) aircraft. Following their arrival, the convoy of guarantors arrived, and the aircraft was searched.14 At 1.25 am on 8 February, the plane departed. On board with the hijackers were 13 Singapore government representatives acting as guarantors of safe passage, 2 Japanese government officials and 12 JAL crew members.

The Singapore guarantors – comprising eight government officials and four Singapore Armed Forces commandos – were led by S. R. Nathan, who was then director of security and intelligence at the Ministry of Defence.15 Besides Nathan, the other guarantors were Yoong Siew Wah, Tee Tua Bah, Seah Wai Toh, Andrew Tan, S. Raja Gopal, Saraj Din, Tan Kim Peng, Gwee Peng Hong, Teo Ah Bah, Tan Lye Kwee, Haji Abu Bakar and Haji Rahman.16 This large number of officers was to reassure the hijackers of “adequate capacity” to ensure their safety. The two Japanese officials on board were Toshioko Tanaka, director-general of the Foreign Ministry’s Middle East Bureau, and Isao Dekiba, an interpreter.17

During the flight, the bombers kept to their allocated area at the back of the plane.18 They said they wanted to “express their dissatisfaction” with the oil companies and visit Singapore again as tourists.19

Upon arrival in Kuwait, the Singapore party handed the matter over to the Kuwaiti and Japanese governments and returned to Singapore, arriving the following day on 9 February. Following the Singapore party’s return home, Nathan conveyed the hijackers’ apologies to the Singapore government and Singaporeans. The hijackers said they had meant no harm to the country.20

Had the hijackers successfully destroyed the Shell refinery, there would have been a shortage of oil in the region for at least a few years, as Singapore was the world’s third-largest refining centre, supplying oil to regional countries.21 The incident is considered as Singapore’s first encounter with international terrorism.22 Singapore’s response was significant in that the country could not be seen as soft on terrorism, lest it becomes a terrorism target again.23 

While the government managed to end the crisis without any loss of life, it was more drawn out than desired.24 Through the Singapore government, the hijackers had sought the help of the North Korean government to escape to an Arab country. However, Singapore’s consultations with North Korea had led to nowhere.25 The hijackers also asked the Japanese ambassador in Singapore to arrange for a plane out of Singapore, but the Japanese government's initial refusal to provide the aircraft led to a delay in their departure.26
