Police are still investigating the incident where a tourist bus went off the road killing four Asian tourists earlier this week.

Eight tourists were in the bus which left Nadi to the Nausori Highlands for sight-seeing when the tourist bus went off the road.

Director Traffic SSP Ramend Raj said investigations are underway as the tourist bus sustained severe damage and they are yet to determine the cause of the accident.

Three people are still admitted at the hospital including the driver.

Meanwhile, police investigations continue into the accident at Savutalele, Tacirua, which claimed the lives of four people, who were passengers in a minivan that collided with a PWD truck last Monday.
