NILAI: A Chinese citizen has been detained after allegedly leaving his 12-year-old son by the road near the Nilai Toll Plaza along the North-South Expressway, in an incident that went viral yesterday.

Nilai police chief Superintendent Johari Yahya said the incident stemmed from an argument between two siblings in the car, which angered their father.

He said Nilai police criminal investigation division personnel, led by Inspector Mohd Azuan Saad, arrested the 45-year-old man at a house in Jalan Cheras, Taman Pertama, Kuala Lumpur, at 12.15pm today.

"The suspect showed the team the car used during the incident before police seized it as evidence at the parking area of his residence," he said in a statement.
