Two workers died and nearly 100 were injured when a truck overturned on Friday in Kampong Cham’s Cheung Prey district.
Driver Chhai Kimheng, 34, fled from the scene but was arrested on Saturday.
Provincial police chief Em Kosal said he was being questioned at the provincial police station.
“We will send him to court after we complete our work,” Mr Kosal said.
He added that the driver caused the accident by swerving hard.
A provincial police report said the workers, whose injuries varied from slight to serious, were sent to hospital.
Three seriously injured workers were sent to Phnom Penh and another was treated in Cheung Prey district referral hospital.
The Labour Ministry said it regretted that the accident happened. The ministry would help the workers and their families through the National Social Security Fund, it added.
Provincial Governor Kuoch Chamroeun visited the workers in hospital and distributed aid to them.
He posted on his Facebook page that it was incredible an overturning truck should cause nearly 100 workers to suffer, including the driver’s wife and sister.
“There were too many people riding on it. The truck could not take it,” he said.
Seang Yaut, a legal officer at the Coalition of Cambodian Apparel Workers Democratic Union, said yesterday he did not know the details of the accident, but was sorry to hear that garment workers still faced traffic accidents.
He said factory owners had a responsibility for workers’ safety, and the ministry and local authorities also had to pay a lot of attention to the security and safety of workers.
“The workers will still face the same problems if they are not cared for by the relevant institutes,” Mr Yaut said.
