PORT DICKSON (Jan 4): Malaysian police on Thursday (Jan 4) obtained a four-day remand order against the driver of a tipper truck that crashed into the car of a Singaporean family in the town of Port Dickson, killing all four of them.

The 54-year-old suspect, clad in standard lockup attire, was taken to the Port Dickson Magistrate's Court court at 8.35am on Thursday for the application of the remand extension to assist with the investigation, Malaysian media reports said.

The truck had crashed into the family's multi-purpose vehicle, a Honda Stream, and three other vehicles at around 2.30pm at a T-junction in Jalan Lukut Sepang on Wednesday.

A preliminary probe has found that the driver was going downhill when he apparently lost control of the vehicle, The Star reported. A video of the crash showed that the truck was speeding through the intersection before colliding into the vehicles.

The driver's blood and urine samples have also been taken in order to determine if he was under the influence when he was driving.

Mr Rosli Samad, 54, who was driving the family in the Honda Stream died en route to Seremban Hospital. The passengers -  Madam Maimunah Sapari, 51, Ms Nur Amalina Rosli, 21, and Ms Dayana Sarah Rosli, 18 - died at the scene and were taken to Port Dickson Hospital. They were believed to have been travelling on holiday.

The Straits Times understands that Mr Rosli was the owner of R S Bikes Centre, a motorcycle dealership in Kaki Bukit. He also has two older sons - one of whom helps him manage the dealership.

Mr Rosli's brother, who lives in Johor, arrived on Wednesday night to identify the bodies.

Mr Rosli's eldest son, along with other members of the family, was at the Port Dickson Hospital on Thursday morning. He was teary-eyed and distraught as he was comforted by family members. When approached by The Straits Times, he apologised and said he was unable to speak to the press.

At least three Singapore-registered cars and several motorbikes were seen at the hospital. The family members were also seen consoling Mr Rosli's oldest sister when she broke down. The group later headed to Seremban Hospital, where a post-mortem on Mr Rosli's body was done.

All the bodies were later released to the family.

Mr Rosli's second son has remained in Singapore to settle the burial arrangements, according to his aunt.

Bernama news agency had reported that based on preliminary investigations, the truck coming from Sepang had hit the motorcycle before skidding onto the opposite lane and hitting the Honda Stream, a Mercedes-Benz and a Perodua Myvi.

The motorcycle rider was injured while the occupants in the other vehicles were not seriously injured.

A police spokesman said the driver ran off after the accident but later gave himself up at the Lukut police station.
