The single-vehicle crash was reported at 2.25am. Six firefighters from Sibu Jaya Fire Station were sent to the scene. No one was trapped, but one woman was still inside the bus and was helped out by firefighters; the other 42 people had already been assisted out by members of the public.

The injured — 19 women and four men — received initial treatment before being taken to Sibu Hospital and Kanowit Hospital. Police, Health Ministry personnel and the Civil Defence Force also took part in the response, which ended at 4.50am after firefighters ensured the scene was safe.

The latest reports did not state what caused the crash or whether traffic arrangements at the roundabout changed afterward. Drivers using the Pan Borneo Highway through the area should follow any police directions and slow down near the scene.
