KUALA LUMPUR: Malaysian rescuers found a fourth body at sea Monday as authorities said they may soon end the search for 36 other Indonesians missing after their boat sank on the way home to celebrate Eidul Fitr.

The wooden boat was believed to be smuggling 44 people including women and children from Malaysia's southern state of Johor to Indonesia's Batam island.

It sank in rough seas late Thursday and four men were rescued the following day.

Asharudin Che Ami, an official with the Malaysian Maritime Enforcement Agency, said authorities may call off the search Tuesday after just one corpse was recovered early Monday and three on Sunday.

“The body was found by a fishing vessel, and MMEA has recovered it. Chances of finding any survivors now are very slim,” he told AFP.

The boat capsized in high waves about 13 nautical miles off the coast with maritime authorities saying it was “not seaworthy”.

The passengers are believed to have been illegal migrants who came to Malaysia to work but wanted to return to their country to celebrate Thursday's Eidul Fitr, the end of the Muslim fasting month of Ramazan, without passing border controls.

One of the survivors found on Friday said he paid some 1,300 ringgit ($400) for what was to be his first trip home in 13 years.

An estimated four million foreigners, mostly from poorer countries in the region such as Indonesia and Myanmar, work in Malaysia — many illegally. They fill low-paying jobs shunned by locals on plantations, construction sites and in factories.

In mid-July, an Indonesian woman died and seven people went missing after their wooden boat capsized off Johor.

Twenty-seven Indonesians, heading to Batam without valid travel documents, were rescued.
