They have been transferred from Slim River hospital to Teluk Intan hospital.

Tanjung Malim acting OCPD Md Tahir Kasim said the chartered bus, which was ferrying students from the school to Kuala

Inside the ill-fated bus

She was inside the ill-fated bus when the trailer rammed into it.

Alor Setar Wanita Umno chief Sharifah Maznah Syed Kassim said Basarah and several others had come down from their bus to help the students.

They managed to take three students out of the overturned bus before the trailer hit it.

"Our driver asked us to return to our bus because of the danger that the other bus might explode. We went in but realised that Basarah was not with us," she said.

"We returned to the scene and were told that she had died in the accident."

She recalled hearing cries from the students and tried to help them in the darkness.

Md Tahir also said investigation was under way. He did not rule out negligence as the cause.

The rest of the group sustained minor injuries and were given outpatient treatment at the Slim River hospital.

The 25-year-old bus driver and the driver of the trailer lorry have been detained for questioning.

There were 41 people in the chartered bus comprising 36 students, three teachers and two drivers.
