District police chief ACP Sum Chang Keong said the driver aged 51 could not be charged yet as police had not received the relevant report from the Computerised Vehicle Inspection Centre (Puspakom).

“We submitted the investigation paper to the deputy public prosecutor yesterday; when the Puspakom report is completed, we will refer the case to the DPP again,” he told reporters after a “High Profile Policing” at Tesco Pengkalan here today.

Sum said police had also recorded statements from the other vehicle owners and passengers in the bus.

Brake failure was believed to have caused the bus to ram into the 10 vehicles at Km265.8, North-South Expressway, south bound, around 2.45pm.

All the passengers in the bus and the driver, and occupants in the other vehicles escaped unhurt except for a 21-year-old woman who complained of pain on her abdomen.

The bus was found to have 63 outstanding summonses for various offences while the driver has nine outstanding summonses for various offences including speeding, between 2011 and 2015.
