It said the express boat was full when it departed.
No reports of casualties are available yet.
Belaga District Office Abdul Halim with Belaga OCPD DSP Bakar are about to go to the site.
The boat was too full to pick passengers from Belaga this morning and as such many civil servants could not board including three Kapit Resident’s Office staff.
Assistant Minister of Culture and Heritage Liwan Lagang, who is Belaga assemblyman, was also among those who could not board.
Last night Belaga hosted the district’s pre-Gawai gathering, so many were in the town to attend the event.
