Kuala Lumpur traffic investigation and enforcement department chief Zamzuri Isa said the incident occurred around 11am on Saturday at a traffic light junction on Jalan Ampang in front of Gleneagles Hospital.

The victim, 49, had stopped at the junction in her Jaecoo J7 when the blue Toyota, which was headed in the opposite direction, veered to her lane before crashing head-on into her vehicle.

The impact caused the Jaecoo to back into a Lexus RX200T that was behind it at the junction.

“The accident was caused by the driver of the Toyota, a 57-year-old man, losing control of the vehicle. He claimed it was because he was having some sort of heart problem.

“When met by investigating officers, he seemed to be in a stable condition,” Zamzuri said in a statement, but gave no further details on the medical issue or treatment, if any, received by the man.

He said the driver of the Jaecoo suffered minor injuries to her hand and legs,  while the driver of the Lexus was not injured.

The police were responding to a widely shared Facebook post by a person who claimed to be the driver of the Jaecoo, with dashcam videos of the incident.

The case is being investigated under Section 42(1) of the Road Transport Act 1987 for reckless driving.
