The boat set sail in the waters of Sumbermas in Indramayu District at around 4 p.m. local time on Thursday to supply freshwater to a fishing vessel anchored in the waters.
However, high waves hit the boat, and it sank in the waters.

The police have continued to look for the two missing passengers with the assistance of local fishermen.
"We are still searching for the two missing passengers," Marzuki added.
