SINGAPORE ~ Singapore police were on the lookout this week for illegal immigrants, believed from Indonesia, missing after a deadly weekend police chase at sea.

Police believe two illegal Indonesians disappeared after the tragedy that left two members of the Police Coast Guard (PCG) and one illegal immigrant confirmed dead.

“Police patrol officers are on the lookout for the other illegal immigrants,” police spokeswoman Cheryl Foo said.

The incident happened last Friday night off Tuas on Singapore’s west coast, police said.

Two police boats were on patrol in Singapore waters when a speedboat with about six people aboard illegally entered the area, a police statement said.

“The two PCG boats gave chase. In the course of the pursuit, there was a collision between one of the PCG boats and the intruding vessel. As a result, one of the PCG boats as well as the speedboat capsized,” it said.

Two officers were rescued with minor injuries from the capsized police vessel. The bodies of their two crewmates were recovered Saturday morning, police said.

Three illegals were rescued alive and the body of a fourth was recovered, they said.
